there is no advantage. Windows 8 is the worst OS I have seen from MS in a long time. I can even get along with Vista these days, but this Windows 8, forget it. It's not just the horrible UI either and it's not me just not wanting to change. I have gone through the ages of the Win 2000 to the XP interface, then to the Vista and 7 interface, I am not opposed to change, I just don't prefer to change to something so ugly and user un-friendly.
Stick with 7.
