Help Picking out a laptop!!! noobie.

Hey:

I'm kinda new to laptops. i have always ran on Desktops because im a graphics designer. and i like speed.. and high power. well after fiddling with my desktop for a few months. i decided its not worth trying to fix. so i decided to pickup a cheap laptop to surf the web and do some minor graphic work in. But im not Qiuet sure whats good whats not. I guess its comes down to im not quite sure what brand is good for laptops..i ussally build my own rigs. i was on a Q6600 4gigs of ram 8800gts,600wat power, msi mobo...that burned out. so any advice would help..i was told to stay away from dell...My budget i would like to stay below a 600$..I am a college student and would like it light...also..just cause i dont want to have it weigh me down..


I was looking at a Toshiba Satellite L305D-S5934
AMD Turion™ X2 Dual-Core Mobile Processor RM-70
3gigs of Ram ddr 800mhz
250 hd
5.4 screen
ATI™ Radeon™ 3100 graphics
Windows Vista 32Bit

For about 399$

Vs. a

HP TouchSmart Tx2z
AMD Turion 64 X2
4Gigs of Ram
320HD
12.1 Screen
Windows Vista 64bit

For about 600$ (I like this one do to the fact its a tablet Laptop)


I am currently on' an old dell latitude 12.1 pentium III 400mhz..so anything is an upgrade form this... .. although it runs great for being so old.

Thanks for your time guys
any advice is appreciated.
