Tethering (Wireless Internet Via Cellphone)

Does anyone here do it?

I'm looking into buying a laptop (wanted to build one myself but it's looking out of the question now) and I've heard of and researched a little information about a thing called tethering. Tethering is when you connect a chord from your cellphones Bluetooth to a USB port and you can leech internet off it (some third-party software may be required). What I'm asking is does anybody here do it? Where can you buy the equipment need to achieve this? and is there a website or two you can give me to find out more about this?

I think this is an awesome thing to do as it is cheaper than wireless internet if you already have a cellphone (maybe costs $7 for unlimited internet). I heard the speed is about twice as fast as dial up. So 56kbits/s x 2 = 112 kbits/s. So about a 14kbytes/s download speed. Not bad considering I'd mainly use it for email and maybe a little browsing.

I'm hooked to IE...JK. It's hard to keep a straight face saying that. I actually use SeaMonkey, which is just Firefox and Thunderbird combined. I'd really only use it to receive emails so speed really isn't a huge issue. I plan to get my services through Virgin Mobile so I'm not sure how this would work, but I'll contact them through their support and see. Thanks for the help.
