You've never had anything in the same Linux distro break after years of use? Seriously? Somehow I find that hard to believe. Even the most skilled Linux users have had things break on them. Just to name a few, PulseAudio used to (maybe still does) have tons of issues such as sound simply not working anymore after a reboot (I had to just uninstall it, so it just used Alsa all the time), package managers get messed up after version upgrades (apt-get vs aptitude) and give you unresolvable dependencies (happens often when libc is upgraded), X window servers get busted all the time too (even just using tmux will mess up your DISPLAY variable sometimes). Google any of these issues, and you'll see tons of people having the same problems. Maybe you're a genius and can fix these problems right away, but not everybody is like you. You also talked about OSX's new security features. You don't need to do any of that if the App is signed, it's just double click install (though most are drag and drop). For Apps that are less popular, yes you'd have to disable gatekeeper, but that's not much worse than having to add custom PPA's on Linux (those cause a lot of issues too oftentimes). I'm all for Ubuntu becoming an awesome viable desktop replacement, and it's come a long way, but (for me) there's far too many annoyances for now so I'm sticking to OSX for my main machine. I do think it's probably better than Windows now though.
