Easy. I'm already envisioning all the ways this device could make my life easier. I would no longer have to juggle RFID keys to multiple clients' premises. I can lock and unlock my 1994 BMW that uses a long obsolete RF keyless entry system that is difficult to obtain replacement keys for. I can adjust my RF controlled lighting system at home without having to dig for the remote. So much of the world runs on RF that having a device that can speak to everything is invaluable.
