Amazing sound, an easy set-up process, and simultaneous playback in multiple rooms—Sonos' digital audio hub was a game-changer that helped usher in the latest wave of music docks and wireless streaming systems. The ZonePlayer ZP100 used a 2.4GHz P2P mesh network to stream music and read data through network hard drives, while offering a 3.5-inch touchscreen controller with 13 buttons for media control and media information purposes (song title, playing time, songs in queue, etc.). The days of dropping $1,000 on an home speaker system were finito.
