From now on when people ask me why I use Linux instead of OSX and why I refuse to install closed-source, copy-protected software, I'm going to send them to Rob Pike's eloquent description of his self-inflicted torture.
Self-inflicted sums it about nice. He didn't have a USB drive (needed for installation), so he tried a few offbeat methods which didn't work, and he didn't have a bootable backup image (so he had to mess with a lengthy copying process). The only legit thing in his complaints is that Time Machine wouldn't let him restore off his Time Machine backup. The other stuff is self-inflicted.
