Review: Wireless speaker system keeps rooms in sync

Despite all the entertainment options the digital age has unlocked, one-button simplicity is fast disappearing. Take music, for example. A sizable portion of the world's discography is available on demand and often hyperpersonalized to our tastes. However, this access requires clicking, tapping, searching and queuing, rather than punching a single button on, say, a radio.
Meet the Sonos wireless speaker system, which is set up in a way that lets anyone in the house figure out how to pump up the jams. (This can be a good or a bad thing, depending on their tastes.)
I've spent the last week testing a pair of Play:3 speakers, which Sonos introduced a few weeks ago. It is the least expensive speaker the company offers, but at $299 each, these are still luxury items. The costs add up because the Sonos concept doesn't pay off until you purchase units for several rooms.
