OSX is not perfect for anybody

I don't think it's valid to measure OS X popularity by the uptake of Hackintosh OS X. If you want to install Linux or Windows, almost any PC will work, whereas for a Hackintosh you need to be very careful about what hardware you choose (see the front page of the main Hackintosh site: http://wiki.osx86project.org/wiki/index.php/Main_Page ).

I don't think OS X is perfect, but as pre-installed on Macs it's clearly quite usable, and Apple has done a lot of usability testing that shows in the product.

When Ubuntu or Mint are installed and configured correctly they can also be very usable, and they are probably easier to lock down and simplify for people who just need to run a few apps.
