I'm very impressed with this netbook. I ordered mine as soon as I heard they were initially shipping with 5800 mAH batteries and I was pleased to find mine came with one. It is rated 5800 mAh / 59 Wh, and the model number is UM08B52. Windows estimates close to 8 hours of battery life when fully charged and it seems to be accurate. The display is glossy and looks great. It boots very quickly although I haven't timed it. Performance is better than expected - I can't tell a difference between this and my Thinkpad R61 when running Microsoft Office applications or browsing the web. I'm not sure if it has a fan because I haven't heard it kick in yet. It stays fairly cool except when charging. The keyboard takes some getting used to. It has great feel but I can tell it is slightly smaller than the HP netbooks I've tried in stores. As noted in some reviews, the mouse buttons are pretty stiff but after a couple of days I've gotten used to it.
