Put simply, this phone is less Storm "2" and more Storm "1.1" -- a hardware service pack, if you will, designed to correct very specific shortcomings in the original model while preserving the overall concept.
The point is that Android, Symbian, webOS, Windows Phone 7, and the rest of the pack should be able to advance with almost total disregard for the hardware business, knowing they're resolution-independent (within reason) and they can expect to target an ARMv6 or ARMv7 core.
