I didn't forget Blackberry. I tried to develop for it in the past. There were a never ending series of downloads. You had to keep registering, repeatedly filling in the same detailed information before they begrudgingly handed over anything. After filling up my machine with bloatware I was unable to even get hello world to appear in an emulator. The chance of getting anything on my device was zero, and they required all sorts of extra certificates and payment to use any of the useful APIs.

This whole process is part of RIM's DNA. A year ago when they were doing the whole Playbook thing it repeated: http://blog.jamiemurai.com/2011/02/you-win-rim/

Quite frankly I know many former Blackberry users but I don't know a single current one. I have no idea why anyone would even consider the platform.
