As of right now, I don't mind Apple's approach. I understand that from version to version, Apple has decided to change or remove stuff that veteran OS X users are accustomed to but I do appreciate that the core OS is still there but they've added iOS features but you don't have to use them (Launch Pad, Notifications).
As for Microsoft, I'm sure if I actually sat down and just played with Windows 8, I'd get used to it but just from using it for a day, you feel that Windows 8 was meant for a tablet or that's what it's focus is from the way it navigates. It's quite a contrast from Apple's approach. One thing I do like is the like is the live tiles, quick information and I think is better than Apple's widgets.
