The Tablets of MWC 2011: Watch Your Back, Apple

Apple sold over 14 million iPads so far, a huge head start on these tablets introduced or first demoed at the Mobile World Congress in Barcelona this week. The iPad is attacked from all sides: smaller screens, more multimedia blitz or port bonanzas. Can these upcoming tablets show Apple who has the last word in the tablet wars?
