BlackBerry to Cease Sales In Japan

Good points!

All of Apples products are set up with high profit margins. They really don't care as much about market share as you might think. Even rumors of cheap iPhones have been partially responsible for driving down its stock price as of late because cheap iPhones mean lower profit margins and less money coming in. I think they will stay a "premium" brand so to speak.
My 2 1/2 year old is an expert at IOS.Its that easy to use the basics on it. It's getting stale, but I think Apple knows it. They never say what they will do next. They have tons of cash to do anything.
Android has the model for taking market share, but the OS makes nothing that I know of for Google. Go figure.

There is room for Windows and Blackberry just purely from the point of view that there are enough things about IOS and Android that annoy some users.
The smartphone industry changes quickly it seems. 5 years or even 2 years from now will all these players be in the exact same position? I doubt it
