Thirty days ago, you were probably thinking to start with iOS, not just because of the launch of the iPad Mini but also the preponderance of Apps in iTunes
Then Microsoft launched Windows 8 (and the Surface), driving a full-court press to get developers to build apps for the Windows Store
A few days later, IDC came out with the latest numbers, showing Android was crushing everyone, with a 75% market share of new phones sold in Q3.
As a result, some declared that iOS was going the way of the Dodo–until last week, when iOS (especially the iPad) crushed the competition in online purposes purchases on Black Friday.
It has definitely been an eventful pre-Holiday Season in mobile.
With all these different metrics and shifts in leadership, which platform do you pick? The market share leader (Android)? The eCommerce leader (iOS)? The one most familiar to enterprise (Windows)? The one most open of all (HTML5)?
If you are Fortune-500 company with a big mobile budget the decision is easy: build on several. If you are smaller, you probably can only build one or two at most (or at least one to start on first). Which one do pick?
