the battery life issue is dubious. my netbook with default battery lasts for about 6 hours. its advertised at about 9, but thats at low settings, i need a brighter screen. but the point is, 6 hours is still long, much longer than the reported "at most 2".
talking about how netbooks have problems running a lot of programs or powerful programs is obvious. of course an atom processor and 512 of ram is going to have problems with outlook and eclipse open. netbooks aren't designed to replace full powered computers. they're designed to run simple stuff and web apps. if you need more, don't buy a netbook. don't try and roll your razor scooter down the interstate.
screen res and quality is valid, but you kind of get used to it.
