It is so obvious and nobody can see it. BB was not a backdoor to Nokia, BB is the frontdoor. BB had a right product for nokia and had most likely already won an account that everyone wanted. They got it. Not ATI, not Nvidia not IMG.
If you knew anything, you would have known for long time that IMG is not the winner in this game. It had an opportunity and it screwed it up with lack of execution. Now the big players are coming into the handheld market, and the "cards have been dealt". Smart move from BB to get there and join one of the big ones, not entering into a fistfight with any one of them.
Nvidia tried the backdoor with Hybrid and its software, but with the announcement of Nokia alliance ATI is at this point right where it wanted, with BB's product in the IP side and its own hardware products in the upper end. Surely the strategy can fail, and Nvidia can pull out tricks and win other accounts, but if ATI / BB can deliver, they have the volume market in the handheld graphics. Period.
This thread has more vaporware within it than what BB ever was able to create. Give up guys, you have to admit that BB achieved something you never will. And by the way, so did Hybrid. Great to exit in style!
