According to an article in BusinessWeek about smartphones, Android's projected share of the smartphone marketplace is 30% in 2014. Now, 4 years seems like a really long time to some, but I'm sure it will be here before we know it.
Google claims they currently have 200,000 new Android phones being turned on each day in 59 countries. That's an incredible number! Of course, we don't know if all of those activations are new users vs. old phones being reset and reactivated. In any case, I'm a firm believer in Android which is why I've made the switch. (Then again, if I were on the AT&T network, I'd probably be using an iPhone)
