Too expensive and not open enough
Compared to OpenMoko it's too expensive, there's an SDK licence fee to be paid.
The phone hardware is low end to average. You'd expect a phone from HTC with such specs to come in at $350 max.
OpenMoko has no licence fees, is more open and the developer version of the phone cost me $350 (inc shipping). Retail version is expected to be $450.
The specs of the OpenMoko are on the whole better, VGA screen, GPS. With the retail version it will also get Wifi, 3D chip and two accelerometers (like in the Wii controller and iPhone).
