You are generalizing a bit too much.
I use both and am fine with both
I installed Windows on my Mac so I can play VN's and native games well(yeah yeah, emulators and VM Ware, Tried them, they don't work for my needs).
And some college programs require it.
I am perfectly fine with drivers on Windows PC's
It's that the drivers on the mac are unique and the ones Apple gave me are not installing right on Windows 8
Works 100% fine for me.
I just trolled Adobe Flash with Flashblock enabled, hahaha.
