Let the hive mind of Engadget get that for you.
"I am looking for a device that will stream sound from one source to several recipients. For example, I want to stream sound from my TV or stereo to my phone or MP3 player that has radio and Bluetooth capabilities. I have looked into radio transmitters and they seem like a decent choice, but I can't find one that uses external power (USB or from the plug) and I would want one with a transmit range of around 50 meters. Thanks!"
Eric, Moxi does not run on Windows. It runs on Linux. The software version you had did run slowly, but it has been updated and is now quite peppy. (Numerous user posts on AVS Forums will attest to the speed and functional improvements in the current software). Just as dentists have improved their methods since the pliers and no painkiller era, so has Moxi software. (I'm a former Moxi employee)
