Can't speak for the Dell or Aspire, but I have used ubuntu on the eeepc, classmate pc, hp mini(~6.5 hrs on battery) and the samsung nc210. Among these atleast I prefer the samsung, which im using currently(int warranty, good keyboard, ~5 hrs on battery, no driver probs and incedibly cute to boot). You might have to run a few scripts, but driver support is generally pretty good on any netbook(consider ubuntu unr). Also, some IDEs dont display as well on smaller screens, so do keep that in mind.
