It took me a while to get into it but I managed to learn some things about the operating system and its potential.  The screen, although having a resolution display, seemed muddy, like you were looking at it through sunglasses.  The touch response had a noticeable lag and moreover, would blank out for not apparent reason.  This matters got more interesting when I'd have it in tablet mode for use of the stylus.  The screen would go black or large portions would reverse to negative.  I'm assuming that there was a loose wire somewhere.  I called Amazon and they were quick to offer me a refund.I'll try again with another.
