Still, from the consumer side of things there's far less friction/lock-in. Switching between phone platforms brings pain only in app selection, most data (like pictures, calendars and email) is all online and doesn't need to be moved over[1].
The key here like you say are software developers. I think Microsoft is aware of this and their purchase of Xamarin is them taking steps to solve this problem. In the future you could see Microsoft showing developers how they could build their applications for all major smartphone OSs with their tools, allowing them to eat up ground in the app space.
[1] Contrast this to PC vs Mac, where even switching from an old PC to a new PC can be a daunting task, and the risk of data-loss is high.
Re [1]: Windows has included a tool for migrating data to a new computer at least since Vista (I think for legacy versions it was a separate download). It works really, really well.
