Also, if you really haven't updated in three years, that means that you're still running kernel 3.16, which has 81 known vulnerabilities[0], 12 of which are critical. That's the kind of stuff I don't really want to worry about anymore.

So now? Linux and *bsd for paid work. Windows for the desktop. cygwin and mobaxterm ftw. All old is new again.
What operating system allows you to "not worry about" OS security updates, and how is it different from Linux?
In my experience, on Linux such installations are smooth for about a year and a half, and then start failing for cryptic reasons, even if you've done everything possible to pick a mainstream distro, ideal hardware, and keep the machine as vanilla as possible.
(And I say this as someone who's been using Linux since the 1990's.)
I also take care of my parents computer with ubuntu and i have done two major release upgrades and have experienced no errors.
The latest update introduced many problems, though
