Is it better to just get a proper C2D laptop for about the same price? Im just worried about portability an Battery life.
Well portability and battery life will be nowhere near as good as a netbook so that would be a big factor into my requirements for example

11.6"+ netbooks hav healthy resolutions by the way, 1366x768 is a fine res no? enough width for my CS4 palettes and movies and enough height to not block out the bottom of save dialogues
