They say the Zune will have an FM radio tuner. And they say it will allow you to send a copy of your songs to your friends, which they can listen to three times. And they say that this wifi activity may be hard on your battery compared to normal use.
I would way prefer a device that did FM transmitting like the iTrip except that it permitted autodiscovery. You point your device at someone else wearing the distinctive included headphones, and unless they have changed their configuration for secrecy, then you listen to what they are listening to. This would require way less battery use & be just as good for record execs (right?). You might throw some signaling into 2.4gHz, but wifi would be huge overkill. Track info can already be sent over FM.
Isn't that a much more desireable device? Why is my idea broken?
