The on-screen keyboard sucks, the type cover is acceptable, but definitely not great.
I replied to your other rant post [the loooooong list of problems one] and as I said there, I only use the on screen keyboard as I don't have a typecover or a mouse.
I don't have any of the screen or KB issues you mention.
At this point I am going to assume you are playing some sort of odd game and I'll resist from responding to you any further.
I am honesty starting to wonder if you even have an SP3 as you are listing issues I've never seen anyone else complain about.
If you do in fact have one, then you should return it as fast as you can safely drive to the store..
