Miguel wrote in a blog post today entitled How I ended up with Mac about his departure from Linux. He's no longer using the Linux desktop but has found love within the Apple camp.
To me, the fragmentation of Linux as a platform, the multiple incompatible distros, and the incompatibilities across versions of the same distro were my Three Mile Island/Chernobyl.
Without noticing, I stopped turning on the screen for my Linux machine during 2012. By the time I moved to a new apartment in October of 2012, I did not even bother plugging the machine back and to this date, I have yet to turn it on.
Even during all of my dogfooding and Linux advocacy days, whenever I had to recommend recommended a computer to a single new user, I recommended a Mac. And whenever I gave away computer gifts to friends and family, it was always a Mac. Linux just never managed to cross the desktop chasm.
