If you find the Win 8 start screen context switch to be an issue, I'd hate to see you enter a new room in your house... metro apps are for tablets but can have benefits on the desktop, but the OS itself is good or better than Win 7 for desktops, you just launch your app and use it on the desktop. Besides the "omg the screen changed" what really hurts the user in that scenario? Organizing apps will be less of an issue as time goes on, I'm already seeing apps not put a bunch of crap in the start screen, compared to when Win 8 first RTM'd.
