"To Mr. Lazaridis, a life-long tinkerer who had built an oscilloscope and computer while in high school, the iPhone was a device that broke all the rules. The operating system alone took up 700 megabytes of memory, and the device used two processors. The entire BlackBerry ran on one processor and used 32 MB. Unlike the BlackBerry, the iPhone had a fully Internet-capable browser. That meant it would strain the networks of wireless companies like AT&T Inc., something those carriers hadn’t previously allowed. RIM by contrast used a rudimentary browser that limited data usage."

“I said, ‘How did they get AT&T to allow [that]?’ Mr. Lazaridis recalled in the interview at his Waterloo office. “ ‘It’s going to collapse the network.’ And in fact, some time later it did.”

You have to give them at least a little bit of forgiveness for having to deal with AT&T/Verizon for so many years. I guess the constraints by their partners never allowed them to innovate.
