I am sad because of QNX, not BB. I don't know what's the future of QNX if BB decides to follow the Android or Windows 8 route.
Interestingly, RIM doesn't say how much revenue QNX makes for the company. http://tech.fortune.cnn.com/2013/04/05/the-little-known-comp...
It ran under QNX/Photon. It never, ever crashed; QNX's reputation for reliability is well earned.
