I've been thinking about upgrading from Windows 7 to Windows 8, but I am not really sure if I like the way it looks without the start menu. It seems like it was meant for tablets more than computers. However, it is on sale for $39 right now (I think this runs through January 2013). The reviews I have read so far have been fairly positive, with people saying it will take some time to get used too. So...that leads me to this question: Does anyone have Windows 8? If so, is it worth upgrading over Windows 7?
