This is an excellent little sub-notebook. Ive been using it for a while running Windows 7 Professional and I'm very impressed. The build quality is good, the battery life is great at about 7 hours (not the claimed 11 hours, though),performance is very good and the feature set very good as well. The design is stylish. I can highly recommend it! I'm not using it for anything more than the usual office applicaitons (Outlook/Word/Excel) and for conencting to the Internet. The screen is passable as well and it's possible to watch a video when on the road. I rate it excellent.
