I've been developing for Android since 2009. I also own Windows Phones too. I prefer WP.

If WP would achieve just 10% market share in my country, I'd drop Android in a heartbeat.

My app deals primarily with Bluetooth BR/EDR + BLE comms to to external devices. Its been nonstop bugginess.

Nevermind Wifi Direct, which I can't get working on a good day. I keep hoping the opengarden guys will be able to overcome the crappy Android apis.
