Comment $199 too high! (Score 4, Insightful) 217
You can buy a Lenovo S10 with 1GB of ram, 1.6Ghz CPU and 160GB harddrive for $249, and that includes WinXP.
The AA batteries sounds interesting, but since all the netbooks come with a battery, and they are cheap enough to buy an entire new netbook with new battery when anything breaks or wears out.
If this unit was $150 or less, it's slow CPU and AA battery power might make sense. But at $199 it's not worth it.
