I agree with Mr Nape that there is an inhereit problem with wifi, 770 and voip. The device can't be online all the time, or the device will have to adapt an even better power saving for the wifi.

OTOH, 770 could be really nice for making the calls. Also, if it had a nice desk stand, that might also rock pretty well for the waiting for call times. We'll see how it goes. Tomorrow.
