The screen is quite amazing, better than any tablet I have personally used. YMMV. Battery life is to me very good, lasts all (working) day (9-12 hours) but I charge it as soon as I am home from the office overnight. One thing is completely apparent: this device was not intended for the careless user. I am extremely gingerly with it and feel like it can last if I do my part but I don't believe Asus intends for me to be using this device in 24 to 36 months time, despite costing $500. Did I mention it's fast? It's really fast.
