The T-Mobile announcement was very specific that the platform for the device was to be Google’s Android. It appears that iRiver’s Wave-Home Multimedia VOIP Touchscreen Entertainment & Communications Hub could also be a candidate. While few specifics are known about this device it has the requisiste 7″ touchscreen LCD, VoIP/DECT capability and hosts “widgets” to extend its functionality.
With a projected availability well in 2010 it’ll likely be a while before we know more. But in either case it’s something that could be an interesting option for our home phones.
