The Tablets of MWC 2011: Watch Your Back, Apple

Mobile World Congress 2011 was the launchpad for tablets from tech heavyweights LG, Samsung, HTC, Toshiba, Acer, and ViewSonic. Here is a roundup of what debuted.

Top 10 MWC Tablets Challenging The iPad

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?
