I have been using Asus Eee PC 1015 PEM for 2 years now. It did break down on the first year but only because I was careless and it overheat. Good thing it still had warranty. It only cost me $300. Battery is good. I can use it even for graphics-heavy programs. However, it's an old model. You may try the latest. Also, I am looking to replace it now with any of the Hp Mini 210 series models. I only use my netbooks less than half of the time (i.e., when outside, to listen to music, etc). They are not as fast as my desktop and laptop but gets the small jobs done.
