But the Cisco version is becoming the defacto standard - folks have given up on IEEE. Soon we are going to see WiFi added to Cellphones (standard flip phones) (I know iPhone, etc already has WiFi to use if available because 3G is too slow - particularly AT&T overload).

The cell phones are headed in the direction of - if WiFi is available your calls will go over WiFi and not the cell network. So when you have WiFi in your home and use your cellphone - your call will route over your WiFi connection and not overload the cell network.
