Colour me skeptical. The biggest problem, as I see, with all these phones is the obsoletion rate of software. If they had pledged to do their best to keep the platform running on the oldest of Android phones, all those phones would immediately be given away or sold cheaply to poor people. They don't need to port all bells and whistles to each of their previous platforms, just the minimum required to keep simple apps (not games, not multimedia) running across all devices. I have a few such "obsolete" devices myself. The only thing wrong with the hardware is that their easily replaced batteries are dead. I'd certainly give them away if they could be of much use now.
