My experience with the TI reference designs I have started with is that they are very good. A lot of vendor references don't even come close to being electrically stable (once you get 'em going) let alone run software. I think TI is and should be a natural choice for more product, and no I'm not part of TI marketing but I recognise good products when I use them.The OMAP family is first class, but it should be, these people know how to do this well.
I think it is not strange to see TI has so many sockets associate with its OMAP CPU. It just means RIM is not doing much change on the reference design from TI. This may also has two implication. One, the TI reference design is so powerful and optimal that people can stick to it and forget about optimization on particular hardware performance. The other possible is that RIM is running out of time to have a very detail design so they just stick to the reference design and cross the fingers to hope everything runs right at the first round in order to shorten the time to market.
Its a masterstroke from RIM to support Android Apps on QNX. This give them complete control of innovation of the QNX i.e. not dependent on Google's mood swings on OS release (honeycomb)and have access to very popular and growing Android Market.
I am sure this will win market for RIM..
