Beautiful OnesThere are few gadgets more beloved among the Technorati than the Sonos Wireless HiFi System. Even though a system could easily run north of $1,000, it made the whole-home audio system approachable. The Sonos Play:3 now offers it to the masses. The Play:3 can stream music from an iTunes library on a Mac or PC, as well as connect to raft of online services such as Pandora, Rhapsody, Sirius XM, Spotify, and many more. Because it does all of that wirelessly, the simple 5.7-pound connected speaker has only volume up, down, and mute buttons on top. And when you can scrape together a few more dollars, you can easily add a second Play:3 to your music system.
