While Linux usability can always improve, what's breaking Linux desktop adoption is that 1) there isn't a good enough reason for most people to switch to Linux, and 2) there are compelling alternatives in the tablet market. I know a few non-technical people that I got to use Linux, now they all have iPads. I went from many support calls (Windows), to a few support calls in between (Linux) to almost no support calls at all (iPad). (They still have their Linux computers, but they use the iPad.)
