I've been enjoying this phone, and to be honest, that's not something I expected. My experience with Microsoft's Mobile OSes -- going all the way back to Windows CE -- hasn't been good, and the last Nokia phone I used regularly was some turn-of-the-century model (the 3360, I think). But the Lumia 900 was a surprise, from its sturdy-yet-slim form factor, to its great AMOLED display, to the complete usability of Windows Phone 7.5. I can't switch from Android; there are too many apps I use regularly, from MLB At Bat to all of the Googleverse apps, to Skype, and, now, to Instagram, that just aren't available on Windows Phone. But if the platform matures and developers support it, there could be a Windows Phone in my future.
