Somebody at Gizmodo shares some very logical reasons for sticking with Windows.
“But really, when it comes down to it, the main reason I still use Windows is this: I’m stubborn and lazy. I don’t want to switch because it will amount to admitting that I’ve been wrong for the last 15 years or so. And it would be just a huge pain to do it even if I swallowed my pride, having to relearn all the shortcuts and commands and little nuances that make an OS tick. I know all those for Windows already. I am just far too lazy to relearn OS X, and I don’t care how easy you claim it is. I’ve made my choice, and I’m sticking by it. At least until I buy my next computer, because I sure as hell don’t want to have to use Vista. I mean, I like Windows, but I’m not crazy.”
I was NOT a Windows power user (even after all those years) so the switch was easier for me. But completely understand why someone wouldn’t.
But for moi, a day doesn’t go by that I don’t discover some useful new feature in OS X. Or some amazing Mac application that makes my life easier.
