I'm going to agree with Anamaniac for my Ideal laptop. 11-12" screen in 1280x800 or 1366x768, because that's what most websites, etc. are designed for, And I'd like it in the smallest chassis possible. I'm tired of all of these manufacturers building a 2/3" surround around the screen. Congratualations, you built a cheap 12" laptop, but It's just as big as a 14". We buy laptops with small screens because we want more portability, not because we like small screens.
Personally, I'd like an AMD dual core at 1.6-2ghz, and an ATi 5200, with 4 gigs of whatever type of RAM you please, and any kind of HD you want, as long as it's got about 100gigs of space, and good battery life. I've got a giant desktop at home for whenever I need to edit videos or play Crysis. When I'm on the road I just want to be able to surf the web, work on office docs, and play some light games. You don't need a powerful computer to play Civ4 and WoW.
