We can't wait until everything is wireless, in the meantime we'll have to accept that the major wireless innovations happening right now are in the audio sphere. Belkin just introduced a new and easy way to stream music from your computer or iPhone/Pod to an existing stereo without the need to create or join a Wi-Fi network.
The Belkin Bluetooth Music Receiver has a small pod that connects to your stereo via either RCA or 3.5mm inputs. You can then pair up to six Bluetooth-enabled devices to play through your stereo up to 33 feet away. It's available now for $50.
