Benson, you're correct.

But usually customers want all the functionality of what they own and not have a company dictate that. They could have released the driver and just said "The guys over at PowerVR got drunk one night and wrote the driver for this, so install at your own peril" and then released it to be tinkered with and improved upon to be useable.

So my speculation wasn't exactually speculation. It has a basis in reality. They could have just been saying that honestly because the PowerVR MBX was crap or they were shot down by beancounters. That's speculation.

Whatever the case may be, I find it hard to believe PowerVR spent all that time designing a GPU and then end up not getting any money back out of it because they wanted too much money for the software to drive it. Even if they had lost money on selling the software at a loss, they would have at least regained some of the capital they invested; reducing the total monetary loss in the end.

So...my bet is that Nokia didn't think of it as a priority and didn't pay to license it. But now that there are competitors with a functional GPU, the incentive to reconsider that decision may be greater. It happened with HTC. They finally bent to customers' demands and competitive pressure and included Imageon drivers in the Touch Diamond, albeit giving existing customers the cold shoulder.
