Asus EEE PC 1000HE
For those of you looking to buy a netbook, the Asus EEE PC 1000HE is among the best (imo) and is on sale at Staples for $399.96. Not sure how long this deal will last.
I can recommend this one. I've had one for about 1.5 months now and it doubles as a travel laptop and a take anywhere in the house. Its not the lightest, but has phenomenal battery life, and the keyboard is very useable, unlike many other netbooks. Performance is excellent also if you increase the RAM to 2Gb.
