iPhone envy will be ever so slightly less now that Sonos has released an Android version of their iPod/iPad/iPhone remote control App. Designed to run any and all Sonos wireless music devices, this App was one of my top ten reasons to buy an iPod Touch in the first place.
Here's a link to a video showing some of the App's capabilities. All I can add is that if the Sonos Android version is identical to the iPod/iPad/iPhone version, it will make your world a better place. I use my Sonos iPod App at least twice a day and it's never failed to do exactly what I want, instantaneously.
