The display does not bother me at all and I personally don't see anything wrong with it. I prefer the Mini over the Nexus 7 one-hundred percent! There is no contest between the two, IMO. I'm not fond of Android nor its laggy nature.
have both the mini and the nexus7, prefer the form factor of the mini over the 7, but i actually like the screen of the 7 better, as for os's, apple has the polish and jb has the better functionality
