Android would overtake Blackberry?
Android as 2nd place worldwide ... that would mean not only jumping over iOS, but also the Blackberry share. Now that's impressive, given that the BB OS market share is still twice the iOS share. Even then, Symbian is still big in the smartphone market; its market share is still pretty high, last I checked Symbian had a 40%+ piece of the pie. So Gartner's 2014 prediction isn't far-fetched ... but Android leapfrogging RIM this year is kinda far-fetched. However, this prediction also means that iOS isn't going to be anywhere near the top three by then.
Now if Android does pull off that prediction ... the smartphone market is going to get very interesting.
