I was just researching these myself. The ASUS EEE PC seems to be best reviewed and has the best battery life and a comfortable keyboard. Sony just came out with a netbook version of their VAIO that has a higher resolution screen, but the keyboard is less functional and I think the battery life is not so good. Basically netbooks are ok if you just want to check email and do some browsing or word processing, but they are very slow for multitasking. Processor speed has been sacrificed for price and battery life, seems like. However, I will probably eventually get one for travelling, but will wait for one with good battery life, a good keyboard, and higher resolution screen.
