The Mac was apparently designed by a person I can't freakin' stand. I recently spent a year with an OSX laptop, and it was a merciful relief when I was finally able to get the hell out of iLand. My first love is KDE because it bows to my will like nothing else, as a good window-manager/OS should. Win8 is also pretty malleable, even though it's not so good for those lacking the chops to bend it to their will. OSX, by comparison, is a constant freakin' PITA if you don't happen to be the "single person" it was designed by and for.
This might be a bit of a rant but I'm sick of people ragging on Windows for its default settings. Windows is eminently customizable. If you aren't a complete n00b you can bend Windows to suit yourself far more easily than OSX. KDE absolutely spanks them both, but still... I would wholeheartedly recommend OSX or iOS to my grandmother, because she's not so good at customizing things. This blog is aimed at people who probably aren't running their OS on 99% default settings. Customizability matters, and Windows fucking owns OSX in that respect.
