Mobile World Congress

Allow us just a little bit of inside baseball here: Mobile World Congress -- Europe's premier mobile event -- has announced that it's staying in Barcelona, Spain, through 2018. We've attended the past three years, and Android definitely had a huge presence in 2011, taking up a good part of an entire hall with a huge exhibit featuring just about every Android phone in the world, and a host of developers.

Mobile World Congress 2012 is scheduled for Feb. 27-March 1.
