My biggest personal tech find of 2011 has to be the Sonos home audio system. I got a review loaner and bought one within a day. I was that impressed with it and continue to love it. You can read the the initial review here and read the review of the new, smaller PLAY:3 here.
During the inaugural Gear Fest last summer I had Carly film a quick walkthrough of setting the Sonos system up. It never made it into a post… until now.
