There is a netbook killer out there and it's called the Latitude D420/430. I got mine on ebay for just $190 in really good condition (avg price is around +/- 250.)
Latitude D420/430 comes with a "real" processor (Core 2 Duo @ 1.2 ghz) and a "real" screen resolution (1280 * 768). The best part about this is that its 3 lb chassis is entirely made of magnesium alloy. Unlike other shiney laptops and netbooks out there, i can just throw it in my backpack without worrying about it getting dinged or scratched
