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!"
(1) You can be sure there will be hype in abundance
(2) When it is first delivered, it will have rough edges
(3) It'll takes some time to smooth out the rough edges. Years, in fact.
(4) And even after all that, it still may end up being a dud (HD-DVD, Vista)
This applies to folks who got Blu-ray and HD-DVD players as soon as they came out, and first-generation plasma displays, and so on, and so on.
While 3D TV sounds very exciting, conceptually, I hope nobody gets offended if I just sit out this dance until the units are actually in stores, proven, reliable, we have 3D content readily available, and we've addressed the first wave of "gotchas" nicely.
