If you hate Ubuntu so much, what do you not hate?
My Ubuntu laptop died, so I was using a MacBook Pro for a few months. I hate it, too, but not as much as I hate Ubuntu.
Now I got a new laptop with Windows 7. It has some annoyances and stupidities, but the overall experience is much better than Ubuntu. (Still running Ubuntu in a virtual machine and a desktop, so I will still complain, just less often.)
So it’s not so much a matter of which OS I hate, but which I hate more. Ubuntu is the worst of the three by far.
Windows 7 > Mac OS ≫ Ubuntu
