What's the most important feature of the gPhone?

With so little information available about the so-called gPhone, users can only imagine what its features are. One would imagine that a good quality phone call is what most users want. If the gPhone can't give you a good signal and clear voice, then would you still want to own one? If the gPhone can provide the entertainment value of an iPod and Gameboy, the ability to do a little work on the side like on a palm but drops calls, then it's just another mobile device.
