Greater than 5 hours battery life and less than $600 is my goal. I want to use this for carrying around a college campus to take notes/browse internet/play simple games/watch videos. If the price is cheap enough I would definitely consider going for a better netbook and buying two batteries.
The Asus Eee PC 1000HE is one of the few currently available netbooks I've looked at, with ~7 hrs battery life and the N280 Atom processor I think it's the one I'd pick if I have to choose now. From what I hear, it doesn't include the new motherboard/chipset that allows HD video playback though which would be nice, and it's a single core. The chicklet keyboard seems like a great idea although I've never used one, and the shift key/arrow keys seem to be in an acceptable place for me. Not a big fan of it's look (looks cheap and plastic-y to me), but it's ok.
The Asus Eee PC 1008 looks AMAZING to me, I know it's basically a poor man's mac book air... but I don't care, it's different. And it still uses the N280 Atom processor, I haven't been able to find out about the chipset yet though. I might have to wait around for this laptop and see what kind of battery life it gets.
Asus Eee PC T101H is something I'd really like to try, never had a tablet and a couple of times wished I did (reading comics fullscreen on a rotated tablet). Not sure I'd want to pay more than $600 for it, and it would need to get >5 hours of battery life for me to consider I think.
HP Mini 2140 is a great looking netbook, and the soon to come enhanced resolution screen 1366 x 768 is better than any of the 1024 x 600 Asus screens. It also comes with an express card slot, but it's main drawbacks (much pricer than other netbooks, god awful trackpad, ~2.5 hr battery life, only has the N270) I think will turn me away. I *believe* there is an extended cell battery that offers >5 hours of battery life, but really don't like the battery to stick out the bottom and put pressure on my thigh when I use it.
EDIT: According to laptopmag.com, the HP Mini 2140's flush 3 cell can last ~3.75 hours, while the 6 cell that stupidly sticks out the bottom can last just over 7 hours.
Should I wait for the N3xx series of dual-core atom processors? Should I avoid any of these netbooks? Is there any others I might have missed that I should reconsider?
Thanks for reading guys, any insight would be appreciated

TL;DR - Tell me what netbook I should buy for less than $600/ greater than 5 hr battery life!
