Sonos

Now you can have instant access to your entire digital music collection, including all your playlists, from anywhere in your home — inside or out. That’s because the SonosTM Controller uses SonosnetTM, our secure wireless mesh network that extends the range of your Controller throughout your entire home. Which means you don’t have to run to your PC every time you want to turn on, change or turn off your music. And, you can control everything from volume to music selection in any room from anywhere.

This is very cool. I’ve been looking for something like for a while. Definitely under the very disposable income entry at around $1200 but very cool. Even does internet radio. Works outside, etc.
