Sleeper HitsApple's AirPlay wireless technology grabbed a lot of press in 2011--but so far, we'd rather have the non-AirPlay Sonos Play:3. Sonos debuted its family of wireless streaming audio products in 2005 with a $1,200 two-room system. In the years since, the savvy upstart has been constantly improving and offering more affordable hardware. In 2011, the company finally broke the $300 barrier with the Play:3, a relatively small streaming unit with a capable built-in speaker. It streams pretty much every online music service you can think of, and you can use your iPhone, iPad, Android phone, or Android tablet as a touch-screen remote to control it. It's a bit hard to explain to non-techies, but once they see it in action, they'll want one. Trust us.
