Ok, I'll admit I'm big on the Alienware Area 51-M, mostly cause it's what I' m using right now, but when I was looking, I was looking for something that had desktop power/speed, but I could lug it around. FYI, one of my first computers was a Compaq Portable 386, speaking of lugging.
Anyway, you might want to check out winbook at
www.winbook.com. They've got desktop processor in a laptop systems too, and they're prices are pretty good.
