What i want for Christmas.....

Griffin iKaraoke -

this coming Winter, the new microphone-based device plugs directly into
iPod's universal dock, transmitting instrumentals and backup vocals (minus lead
vocals) to your stereo using an in-line connection or an FM transmitter. With a
switch to toggle lead vocals off and on and three levels of reverb—now all
you'll need are lyrics.

Thanks to Tony for the info.
