I bought my first RPi in January of 2014 and am now up to six of them.
One using OpenSprinkerPi running my irrigation system.
One using RasPBX with Asterisk running my telephone system.
Three using OpenElec running XBMC.
and one using Volumio to stream my music from my NAS to speakers around my pool deck.
Love the Pi and am getting into Volumio.
