Yep I hear win 8 is a fucking nightmare.
I've used it briefly but only on screen share on skype while helping a friend set up his new computer.

We had to google how to reboot (wtf no start menu) and the control panel seemed to change layout everytime we went into it.
Also I nearly choked when I saw the new task manager, although I hear that is the one redeeming feature to win 8. I didn't get a chance to use it, only saw it for like 2 seconds then my friend closed it down.
