Oh really...I found this the other day

http://homepage1.nifty.com/kyou-kyou/jornada/en/

I still have my Psion 5MX, which I bought after a Psion 5, after a Siena...

It was and still is awesome, and the 3rd party software you could find let it do so many things, from becoming a database for chemicals or medical drugs to fairly complex scientific calculations, reading and writing data to phones, becoming a terminal, programming network hubs, simulations of interacting space bodies... blah blah...

The one thing I pined for initially was a little more connectivity. It obviously wouldn't support CF wifi cards and such. If it had wireless and proper network support I could have been totally happy. Eventually I bought a Jornada 680E for the colour screen and PCMCIA slot but was disappointed by the utterly abysmal backlight and the crappy OS.

I would certainly adopt a revamped version of the Psion, I was so crestfallen they abandoned such devices.

How about a Transmeta?

AFAIK they are not making chips anymore.

As I said, I'm not too familiar with ultra-efficient chips, might be better solutions than undervolted Core Solo ULVs.

I bought a 5mx in 2001, which I still use regularly, mostly for writing novels. They were (and still are) fantastic devices, but I have to wonder if there's much of a market for such a thing these days. Most PDAs nowadays are outsized phones. Those that have QWERTY keyboards at all need a matchstick to use.

The 5mx cost about £400 when it first came out in 1999, or about $600 at the exchange rates of the time - more like $800 now. I'd be reluctant to spend much more than that on a new one.

Those who expect this new device to be a miniaturised laptop are missing the point. Yes, the 5mx was a computer you could put in your pocket, but it was a computer that could do the things you actually needed while you were away from a bigger computer. The main design goals were for it to be small and light, with a long battery life. (Even then, people who'd upgraded from earlier models complained it was too big and heavy, and the batteries didn't last long enough.)

With that in mind, this is what I'd like to see in a new incarnation of the 5mx:
- Keep the overall form factor - clamshell, with a keyboard that slides forward.
- Keep it about the same size and weight. It has to be something you can put in your pocket.

- Keep the keyboard. This was one of the best things about it.

- Keep the touch screen. There isn't room for anything else that does service for a mouse.

- The screen was hard to read on the 5mx, unless you could get a light source in just the right place over your shoulder. It had a backlight, but you had to switch this on, and it ate the batteries. I imagine screens have improved a bit since then :-) It doesn't have to be much higher resolution than the original. Seeing as I deal mostly with text, it doesn't even have to be colour - the greyscale screen is one reason the batteries last so long.

- A headphone socket would be nice.

- One, preferably two, USB sockets. This gives a lot of expansion options.

- Some form of removable storage. The 5mx has a CF slot (picture 11 in the slide show). I don't think it needs SD *and* CF - SD alone should be enough.

- One of the frustrations of the 5mx (in fact, all the Psion computers I used) is that the onboard memory doesn't retain its contents without power. It has a backup battery, whose sole purpose is to supply power to the memory while you change the main batteries. Occasionally, the backup battery gets dislodged, with predictably catastrophic consequences when you go to change the main ones. It's supposed to warn you that the backup battery isn't supplying power, but it never does. So the new machine needs either a better warning system, or else some form of non-volatile memory onboard.

- A VGA port might be nice. DVI would be more future-proof, but do you have any idea how big those things are? Allowing for the screws to hold the cable in place, it would take up half of one side of the machine!

- People are going to want to use it as a phone, but this shouldn't interfere with its usability as a computer. So I think anything that anything you need to use it as a phone, which isn't also useful as part of a computer, shouldn't be built into it. A UMTS modem would allow you to make phone calls, but would also let you surf the net, far from any coffee shops with free wi-fi. A Bluetooth headset, on the other hand, is not so useful just for computing, so I think it should be an optional extra.

- Software. This was the other great thing about the 5mx. Considering the OS and hardware were both proprietary, it had a huge selection of third-party programs available. But the built-in applications were so good that no-one ever seriously tried to replace them. They were unbelievably stable, too. In the whole time I've owned a 5mx, I can count on one hand the number of times an application has lost data.

The OS is still around - it eventually became Symbian - but I don't know if it's a good choice nowadays. Please, please, PLEASE don't put Windows on it. Microsoft already have far too much influence. Windows will make the machine just another underpowered laptop with little or nothing to distinguish it from competitors. Put Linux on it, and make it easy to replace or upgrade. Maybe allow it to boot off the SD card, something like a live CD on a PC.

I've been wondering what will replace my 5mx when it eventually dies (I bought two second-hand Series 5's as insurance against that), so I'll be interested to see where this redesign or resurrection goes. Stay true to what made the 5mx so good in the first place, and I'll seriously think about buying one when it becomes available.

I would agree about phone functionality comments above. It doesn't have to be designed to work as a phone held to the ear, make the phone usable only via headset (bluetooth or not) or handsfree and keep the great form factor.

i think this is a great project

main specs i'll leave to someone else, tho i have soem thoughts

definatly a phone, usable by headset wired or bluetooth

some storage capacity

wireless g at least

as it has to be compatible with windows, i would suggest xp or wm5, but hey give people the option to have linux or whatever if they want

the whole swing screen idea is nice to lend itself more to a pda/phone functionality, but if not, a second low power screen for basic info of call and so forth

its always nice to see some exciting new designs and ideas

I think you're finding the point, one which so many have missed by a ****ing country mile. It's good fun reading these cloud-cuckoo land featuresets though.

Have either of you actually ever used a 200+dpi screen? Because they're perfectly usable, through the twin expedients of 1) changing the dpi/font settings in Windows (or your OS of choice) and 2) moving your head closer (would you really use something with a 7" screen at the distance of a normal laptop?)

I'm happy using my Libretto's old 6.1" VGA (130dpi) screen at full laptop distance; I normally bring it closer, but the pixels get distracting. I have no issues with my T221 (204dpi, 22" ) although I wouldn't want to sit too far back. If I could perch it on my hand without breaking my wrist, it would be fine. Don't mistake small text for pixellated text - the sharpness of a 200dpi screen makes small text perfectly legible.

The reason I, at least, have been advocating something like the screen on the U105 (which is, after all, a laptop intended for running Windows XP) is that for a Windows box, developers (and web designers) target XGA as a minimum screen resolution, and SXGA is more common. I have experience with trying to use a smaller screen (Librettos, Zaurus, Palm, UIQ, Newton) and it's very restrictive. By all means allow for a bit of ctrl+scroll wheel resizing and for people to fiddle the dpi settings (I prefer having real-estate rather than smoothness), but if the pixels aren't there then there's a problem.

This is mostly the case for UIs that assume higher resolution - i.e. running a desktop OS (Windows, Linux, OS X etc.) or platform-independent stuff (html, PDF, etc.) - PDA-centric applications obviously work much better, and I'm not suggesting it shouldn't ship with things that can be used without squinting in that way. I'm just saying that making this an arbitrary PDA turns it into yet another Journada/Nokia 9000 series, and they're not big sellers. Nor have they needed much more processing power to do the job of being a PDA than they had when they were first launched. A real PC in the same form factor (whether or not us geeks would actually leave XP as the primary OS), which I believe is possible, is a much more tempting device. If it weren't, my Newton carry case wouldn't be being used for holding a Libretto.

Speaking for the number of my friends who own(ed) 5mxs and read this site, I'm not sure where that idea came from. The only reason I don't count is that my fingers are slightly too chubby.

Back in '98, I worked for a large financial market as a sys admin and I needed a kick ass PDA to keep everything together. The 5mx was my choice and bought it with my own cash. The best $480 I every spent. I still have it though the keyboard is a little twitchy.

The clamshell should come back. Not only did the clamshell work but the quick buttons along the screen edge worked well too. The current hardware buttons of PDA/Smarphones are too limited and require the user to take the time to learn how to remap buttons to access common functions faster. The only device out there that comes anywhere close to the 5mx is the HTC Wizard inspired devices(I've used the Cingular 8125 for 6 mos).

Windows Mobile still has no built in task manager, 5mx did have an Alt-Tab like Windows.

IMHO, the Psion 5volution (my name for it) shouldn't run any of the current mobile OS'es, they are too limiting. Epoc32 is a well designed OS and if it was made opensource for the 'Nix heads to modernize it for todays hardware, we could see some marvelous things.

I agree with the concept drawings for adding VGA out and USB 2.0. Definitly BT for PAN with headphones, cell, PC connections. Wi-Fi, maybe but I would either make that a trim level option (5volution Premier).
Connectivity was one the things that killed the 5mx from moving into modern times.

Batter life? Despite the problems with Sony's Li-Ion batteries, the technology works for form factors like the 5mx. The backup watch battery though should stay.

Capacity. Std model should have 256MB( this will make it affodable). How about making the expansion a Mini-SD slot. Premier would come with 1 GB internal.

Screen. Still the same measurements but resolution can be set for Low, Med, or High(800x600,Premier lvl) 32bit color.

How about a camera to the rear of the unit? Would only work when clamshell is opened. 1.2Mp, video capable.

Pricing,
Std - $449
Premier - $789(faster CPU, better screen, Wi-Fi, more RAM/storage)

UMPC is a nice idea but won't work in the long run. MSFT will drop it. Watch for stuff out of the Koreans. I think they see the need to break the mold and try new things.

The traditional PDA/Smartphone formfactor is dying. Just like BetaMax and OS/2 sometimes a design is so good that competion can't beat it so they defame it to program the consumer against it. But when brought back, it's still compelling.

I hope device makers happen across this forum because you'll hear what folks don't like about your current offerings and what we'd like to see.

May the 5mx live once again!!!!

I flatly disagree with the phone usage.
If you look at phones they are designed around the consumer cycle and something new and different every few months.

If someone really needs a cellular connection use bluetooth to link to a cell phone.

In my previous rants, I'd not really answered the actual questions. Having had a weekend to ponder it...

We still seem to have two threads going on, intermingled. One is discussing a true replacement for the 5mx: a clamshell PDA. The other is discussing getting an x86 laptop into the 5mx's form factor.

In my mind, the former is obviously possible, because the 5mx *was* one, and producing a faster, colour-screened version isn't desparately challenging with more modern technology. This is effectively what the Nokia 9000 series is, and to me it's therefore a "solved problem", and not (to me) very interesting. I don't need one of those - I have a Sony Ericsson P910i, and I don't need the keyboard that badly. A 640x200 screen would be nice, but I can surf on the P910's 208x320, and if I was going that route I'd probably put up with the bulk of a JasJar (and Windows Mobile), even if the keyboard isn't quite as good, for the extra features and full VGA screen. As I've said before, I can't quite use the Psion 5's anyway. Making something like the 9500 or JasJar but "a bit more like a 5mx" wouldn't add much for me. People may be interested in discussing it, but frankly you can always buy a folding bluetooth keyboard and add it to one of these devices, and you'll end up with a better typing experience than the 5mx anyway. Other than the keyboard I doubt there's enough to differentiate it, given that the other devices are cell phones as well.

On the other hand, a "real" PC that you can stick in your pocket, and run XP (and dual boot to Linux), is far more intriguing. It would be much easier to make something run Win2K, but that would get laughed out of the shop these days no matter how practical.

Given that I'm talking about the "real PC" concept, I'd answer the questions:

1) At least 1024x600, preferably nick the Libretto U105's 1280x768. 800x600 is the absolute minimum for running Windows apps, but at least 1024 across will make an enormous difference both to running Windows apps and web surfing. 1280 is the new common width, and pretty much guarantees everything will work okay. A transflective alternative would work better outside and massively help the battery life, but probably ruin the Windows experience; LEDs are probably the way unless you go with (dim) white electroluminescent sheets (like the green one on the original). [A PDA can make do with much much less resolution, although the more the prettier. Web browsing is the big reason to have at least 800 across. Transflective would help here, and absolute picture quality is possibly less a benefit than battery life when compared with a PC system.]

2) Unless Via have anything lower power than a ULV Yonah, Intel it is. This will be limited by battery technology, and cooling (although a metal case - preferably with some grooves on the back - to act as heat sink will help). It's a huge chunk of the price, but what can you do? 5.5W is a lot for a PDA CPU, so down-clock it and hope for the best, possibly with a "turbo" mode when plugged in. If you need fans (unless they're on the docking station) you're in trouble. [For a PDA, take your pick, but we're probably talking a fast-ish ARM variant.]

3) Memory will come down to space, price, and power consumption. No room to make it upgradable. 1GB would be extremely generous, and 512MB is probably the lower limit. You can always set up the CF-card as a swap drive. [A PDA can use much less - 128MB or so.]

4) Solid state storage if it doesn't price the device out of the market. Don't aim too high - 4-8GB is lots if you're not trying to play games or do a lot of Photoshop. There's always CF drives and USB external enclosures. A small HDD would have some appeal if it can fit in, so long as it's resilient enough (this will probably be more abused than a usual laptop) and the shape isn't a problem. Also HDDs can handle large numbers of accesses (e.g. swapping) better than some solid state drives. Large sizes are, IMHO, useful for video playback (not going to work for long with the battery available - ARM and media processor based systems are much more efficient), big audio collections (if this is really the way you want to re-load your iPod nano) and photo storage (somewhere to download your holiday snaps - I've used a laptop for this before). This isn't a machine for video editing, high end photo editing, or modern games. Making the internal drive remote mount as a USB mass storage without booting up would be a nice touch. [PDA: go solid state, for resilience. Probably don't need that much.]

5) WiFi: Yes, it makes a massive difference to plug-and-play. Even if it could be added by CF card or USB, if it fits in the space (it's on the P990, so it should) it's a huge win. So long as it's usually turned off. Bluetooth is even more useful (use a "real" keyboard or mouse) - especially, use a mobile phone as a modem. Don't try to make a Windows PC work as a phone - everyone has a phone anyway, and you don't want to have to wait for XP to un-hibernate to make a call. [PDA: WiFi is less critical, although it's still nice for a bit of surfing. Bluetooth is still a big winner.]

6) You'll never run an x86 (at least, a useful one) off AAs. If you did, they'd be too expensive to keep replacing, or too annoying to keep recharging. There *are* Li-ion AA cells, which would give you an emergency replacement opportunity if you're two minutes from finishing your presentation and you're nearer a supermarket than a charger, but it's got to be easier to go with Li-ion or lithium poly, just from a form factor point of view. Sell an optional battery pack, either to plug into the charger socket or replace the internal battery (as a thicker lump). Ship with a car charger and, ideally, the ability to trickle charge over USB. [PDA: A decent colour screen will kill standard cells, although the ability to stuff in some AAAs in an emergency is something I miss from old Palms. Still, I think to keep it think you're better with something like a cell phone battery.]

7) I'd lose the SD card reader, and possibly ship a complementary SD-to-CF card reader with it. If that's still not enough space, lose the CF card slot - it's very nice to have for upgrades, but USB can replace most things these days (although they may be higher power). Agreed with the docking station suggestion, although again it's amazing what you can run over USB these days. It should all fit (although the narrow end of the slope at the front will be a bit challenging), but the space left for the battery will be a big question. If I'm reading the spec correctly, the Core Solo is about 3.5cm per side - huge compared with an ARM, but not that much of the total footprint, especially if mounted on the back of the board to heat-sink it. My life's too short to research the chipset and ram sizes in detail, but they look okay, so long as device A doesn't fry device B that's right next to it. 7.5"x3.5"x1" is pretty big compared with what's inside a Libretto once you've taken out the full 2.5" HDD, the pcmcia slot(s) and the battery. If possible, the thickness is obviously the thing to shrink - 1" is a thick device to stick in a trouser pocket, but even 2cm would be much better, and 1.5cm trivial. The Newtons were only 8"x4"x1.2", and everyone remembers them as being huge; my Libretto (a full, old, PC) is 8.3"x4.5"x1.3". [Without using x86 processors you could probably make something half the size.] Tip for both: don't run the PCB the full width, and use ribbon cable for the bits on the end. Then it can flex a bit without damage, so long as the screen is protected.

8) For a PC, $1000 sounds right, if possible. It's not as powerful as some mini-machines. I'd sooner have a machine I can use at a price I can afford than something all powerful that I can only aspire to - don't spend a fortune giving fractional price gains. Sell the docking station and spare batteries as extras. Don't go for the faster ULV Core Solo. Certainly don't add 80GB of solid state storage! This is nobody's primary PC - better it be a handy toy for lots of people than a workhorse for a few. I doubt making it for much less is feasible. I'm curious about the prices quoted before - lower than I'd expect, although I've never tried to source this kind of thing.

I might try doing some drawing myself.

Out of interest, dumb question: is this idle chatter, or (potentially) actually going to happen?

There does seem to be an interesting divide here between those that want a fully fledged PC in the shape of a 5mx and those that want something usable, affordable and reliable. Basically it's a divide between those that want another Sony Vaio style PC (great from a gadget POV) that will be redundant in 3 months and those that actually used (and still use) a fantastic device that delivered what it promised and nothing more. I have used many mobile phone and organisers. I am a gadget addict but none have ever lasted as long or have delivered anywhere near to their promises as much as the 5mx (and the 3 and 3c before it) did.

Personally I would happily settle for a modernised version of the 5mx. Colour screen, modern processor, decent connectivity etc... as long as the software is as good as the EPOC OS and it lasted more that 8 hours on a charge. (Maybe the ability to take AA's when you couldn't charge the Li-ion?)

That put me in my place.

I think that's a little unfair. Which Vaio do you mean, because what we're discussing falls between the form factors?

The Vaio subnotebooks were great bits of kit, but they're enormous compared with even the latest Librettos - 3cm in each major dimension. The latest U105 is a full 5cm wider than my 70CT, which is in turn bigger than a Psion. Those subnotebooks were great for being a full PC that you can carry in a bag easily, and they have a far more "proper" keyboard than the 70CT (which is an acquired taste), but there's no way you could fit it in a pocket. The 70CT would almost fit in a pocket if it were thinner.

The Vaio VGN-UX180P on the other hand, like the oqo before it, isn't a "proper" laptop. It may be powerful enough, but it's got a thumb board, not a keyboard. Even on a table, it would be hard to touch type on properly (although I don't own one, and owners may disagree). The 5mx was much better (although the Revo possibly wasn't). People have complained about the VGN-UX180P update, but frankly I doubt it makes much difference to practical usability for a device this size. In my opinion it's too expensive, and possibly more full-featured than is useful, for something that's a PC masquerading as a PDA.

I think there's a market for something with a relatively decent keyboard (touch-type capable) that will fit in a pocket. I don't think such a device currently exists, unless you start adding folding bluetooth keyboards to the UX180P or oqo.

That's why I think a PC-style device in this form factor would be useful. It doesn't have to be blindingly fast by modern standards (so long as it keeps up with the XP desktop, and even at half the clock a Core Solo ULV would do that); even less so under Linux. Since we're already talking about underclocking it, I don't think we should talk about it being obsolete immediately. My Libretto was launched in 1997, and is still going strong (although it wouldn't run XP). Sure, what we're talking about would struggle with Aero Glass under Vista, but it'll be useful for a long time as an XP, Linux, or even Vista "classic" machine. We're a long way from a work horse in that form factor, but a cheap "carry anywhere" PC that you could actually use as a PC (again, keyboard-determined) is, I think, possible. Actually trying to use either the UX180P or oqo as a generic machine is tricky, at least for a lot of people. Many people don't come near to needing the performance of the machine they've got, and this will never be a gaming or photoshop box anyway.

I can defend the reason this would differentiate itself as a PC from the other devices on the market (a more portable "real" laptop) - and why the shortcomings (mostly performance) aren't such an issue, at least if it's cheap enough.

While I'm interested in the PDA idea, I have to say I struggle more to see where it comes in. The PDA market has gradually been eroded by the smart phone market (as someone who used to carry an 8850 and a Palm, and now carries a P910i, I can see why); the NetBook is interesting but too big and expensive for most and never sold well (with either WinCE or EPOC32), which suggests that the "PDA with a decent keyboard" market is limited - and I speak as a Z88 owner. Is the keyboard on the most direct successor to the 5mx, the Nokia 9500, really bad enough to make it unusable?

There's a question of OS, too. I'm not sure that the keyboard-friendly version of Windows Mobile has ever really caught on. I'm not totally sure I trust Nokia's idea of a GUI, but UIQ3 is, by all accounts, worse (and doesn't support high resolutions). You can run Linux on it (I have a Zaurus, and if it had a reliable battery indicator I'd probably use it), but a proper PDA GUI might need development from scratch. UIQ won't help and Nokia's interfaces are proprietary; even starting with Symbian there's a lot of work to do - especially compared with trying to build something out of standard PC components.

I guess the question is: what do you want to do on it that you can't do on an original 5mx?

Having a colour screen just to make it pretty (and kill the batteries) doesn't help much - although better contrast than the 5mx (eInk?) might be nice. The biggest benefit I can see to upgrading the 5mx is for web surfing, but a keyboard is actually not vital for that (other than forums like this), and no embedded OS has a browser quite as flexible as the desktop OS versions. The Nokia 770 does portable non-phone web browsing pretty well (as did the netbook), and I'm not sure something 5mx-shaped does better. Most PDA uses that could benefit from a "real" keyboard (most notably email) don't benefit all that much from a colour screen, or even a fast processor. I'm not sure the experience on a 9500 is much different from that on a 5mx - in which case, why not just pick up a 5mx from eBay?

Any OS development is either going to have to pick up one of the current ones (for better or for worse) with their GUI and reliability limitations, or start completely from scratch. Don't get me wrong, I'd find this a fascinating project, but it's not a short one. And then you've got no apps. I doubt EPOC32 has been open-sourced while I wasn't looking, although I'm prepared to eat my hat about that one.

Basically: I can see that, with both the Windows version and a PDA version, you can point at other devices and say "why not just use that". I can defend the position of what a Windows (well, x86 with the option of Windows, Linux and maybe OS X) product would provide that's not already on the market. I have a harder time with the PDA idea. However, since I've never tried to use a 9500, and I've already said I can't quite get along with the 5mx keyboard without it gaining a couple of mm, I'm probably in a bad position to judge what would make a PDA with a keyboard usable.

I'm genuinely curious, though - please don't take the fact that I can't see it as an attack on those that can.

I think that's a little unfair. Which Vaio do you mean, because what we're discussing falls between the form factors?

This is true. The problem is trying to decide what market we are trying to satisfy with this new device?

I couldn't agree more here. :-)

Again I agree. XP has been around for a while and is well established. I do have concerns to how well it would work with something like the Psion. The 5 worked well because the device and the OS were designed to work together. Maybe what we need here is a slightly reduced/tweaked version of XP especially designed for smaller devices. More than WM5 but less than XP. Possibly with a new interface that works better with the reduced key count and touch screen interface? Is the Tablet edition of XP any good?

I think I would be happy with using this device as a PDA if it works well enough. Going along with the idea of perhaps a flavour of XP being used as the OS then there is no reason that it couldn't run Outlook.

I guess the question is: what do you want to do on it that you can't do on an original 5mx?

Having a colour screen just to make it pretty (and kill the batteries) doesn't help much - although better contrast than the 5mx (eInk?) might be nice. The biggest benefit I can see to upgrading the 5mx is for web surfing, but a keyboard is actually not vital for that (other than forums like this), and no embedded OS has a browser quite as flexible as the desktop OS versions.

The main reason for having a colour screen would be for web browsing and the occasional viewing of pictures. I also think that it would be hard to find a decent supply of anything less these days. I don't supposed the demand for decent resolution, greyscale LCD screens is that high. I could be wrong of course.

I have a QTEK 9000 at the moment and I really like the ability to browse from almost anywhere but the WM5 browser really doesn't cut it for me. A proper browser would be a real plus for me although this also means that I like the idea of the device being GSM/GPRS/UTMS connected. I'm not so worried about using it as a phone though.

My main point about EPOC is that it did what it did and did it well. I think that to start again with a new OS would be a (nearly) impossible task now so I concede that the choice would have to be from those that already exist. I have nothing against Linux either and use/develop on it every day but I just feel that XP, although far from perfect, is nicely matured now with plenty of decent apps.

For me it all comes back to my desire to have an updated 5mx. I like the idea of something that looks almost identical to the mx but with a newer OS and the ability to run any number of good applications. I used to actually enjoy writing on my 5. It could be used either with the thumbs (if you didn't have a desk to put it on) or (just about) in a touch-type fashion.

The important thing here is to not get carried away. Some of the ideas coming up in these suggestions are great but would only serve to increase the cost, size, weight and heat of this device.

I guess that designing something that everyone here would like might be impossible but maybe we're missing the point slightly. Shouldn't a decision be made as to the intended market for a Psion 5mx replacement before deciding about the hardware/software?

Sure. The screen wasn't actually my point, I'm all for smooth fonts thru high-dpi settings.

Speaking for the number of my friends who own(ed) 5mxs and read this site, I'm not sure where that idea came from. The only reason I don't count is that my fingers are slightly too chubby.
Again, I'm being slightly cryptic, but Baloo touched on it below. Your Tom's forum reader is going to have pie-in-sky thoughts of making a tiny "Pee-cee" in such a form factor - such a thing is both unattainable, and utterly pointless. That would be a novelty. The 5mx was a productivity tool.
