Thinking to buy a new laptop

Hi folks how is everyone today/tonight, i am good i hope everyone is had a good weekend. I already have a computer but recently i had an urge to get a laptop for various reasons which i will state soon.

I read a few laptop buyers guides and have general idea as to what laptops are and what are their uses and purposes. When searching around i came across only two types or categories or processors of laptops [1]Intel and [2]AMD. Now if we sub-categorize Intel based laptops there is Celeron, Pentium 3,4,M, Centrino, Centrino Duo Mobile. If we sub-categorize Amd we have Sempron, Athlon Xp, Athlon 64, Turion 64 etc. Are these different models of processors which came out at different times ? What's the difference between these ? Which one is better performance and price wise ? Are there any more types of laptop processors or just these ?

That will be it for this time. I will appreciate it if someone can explain to me in as much detail as possible regarding these questions so i have a general idea of what kind of laptop will fit my needs. Thanks in advancet

Thx for the reply i will specify my needs as to what i want this laptop for. My main interest to get a laptop is to watch movies on it, also i want to be able to connect it to my tv and watch movies on my laptop on my tv. I also want to use this laptop for playing latest games, listen to music, run big applications like adobe photoshop,winamp,wmp,frontpage, do a lot of web-designing, also need a latest fast cd/dvd burner which can burn cd/dvd of all types/formats. I want a good high quality/performance laptop to do all above but for the cheapest cost available(as many people offcource) because i am on a tight budget i am looking for something below $1300 Canadian Dollars. If possible i am also looking for an option where i can pay for the laptop slowly on monthly bases without getting charged any interest/extra fees.

I would like to know what part to look for in a laptop which will let me connect my laptop to my tv and stream movies/videos at good speeds. Is it s-video port/jack or vga port/jack or something ?

Here are details of my ideal laptop

1.5 ghz + processor
4-6 usb ports
1-2 firmwire ports
512/1 gb ddr/ddr2 fast ram
80-100 gb fast harddrive
cd/dvd burner for all types of files/formats preferrable DVD±RW
good quality for audio and video
a good graphic card/accelerator for latest games
need wi-fi or latest wireless technology to use internet easily
15-17" good quality monitor/screen preferrable widescreen
be able to connect it to my tv and vise/versa to watch movies/videos etc at good streaming speed and good quality

Budget = $500-$1500 Canadian Dollars
What's in it for you = Great appreciation, warm tingly feeling of helping someone desperately in need, getting to find out whats latest in store/ on web nowadays
