Granted, it's relatively cheap considering the hardware. However from a developers point of view, without any released kernel sources it will be like porting Linux to any other device, which means it'll take years. That makes it pretty uninteresting for me. For a user, this phone may be just cool, but don't expect it'll be possible to run your own applications.
Given that the openezx project (Open Linux for the Motorola phones) seems to make great progress, I'm considering buying a A780 and adding support for that into OE.
