I want my desktops beefy and my portables, well portable...
I expect a 8 hour + battery life from my devices and at present, its either a 2000 dollar bomb shell with some Intel ULV, or drop some money into a netbook that will cost 600 tops (incidentally, the amount I saved up for my 5800/GT300 CF/SLI setup).
Also, I'm waiting on this touch based netbooks with a 11 inch screen, because when you look at the damned DELL XT2, it costs nearly 3 grand for touchscreen and these little suckers may just replace the Xt2 on my list of things I want, but maybe not need.
