I really thought about getting into Windows 8, sadly Microsoft disappointed me several times. The biggest one was the Windows Phone 8 launch, which made my development device (a HTC Titan) stuck in WP 7.5.

I've been successful on Android, but I really hate the fragmentation.

I've tried BlackBerry development (got a PlayBook to develop on) and after 2 months working on a app using their HTML5 library bbUI.js my app started to misbehave because of a bug on that library. After 2 more weeks trying to correct this problem I couldn't correct the bug and my problem just became bigger. So I rage quit.

I've been trying a bit of iOS development, but Objective-C is giving me a hard time.
