Scared of Windows 8

I was planning to take advantage of the $40 upgrade pricing for Windows 8 to upgrade my Windows 7 Boot Camp partition. I was going to do this primarily to support my research, but also because Windows 8 looks interesting. I wanted to see if there were any aspects of Windows 8 that were indicative of increased or decreased elegance compared to Windows 7 and compared to other mainstream operating systems. After watching this video review, I am not so sure if I will go through with it. Yikes!
