The battery life on this is terrible.  But that is far from the worst of the problems.  The screen goes blank from time to time for no discernible reason and requires me to log in again.  I was playing a word game today when all of a sudden what I was typing is not what would appear on the screen.  When I typed certain letters, a number would appear alongside it.  Then the screen went blank again and demanded that I log in.  But I can't log in because it misinterprets what I am typing.  So I spent over $200 and now have an ugly paperweight.
