It's a matter of personal UI preference. I just do not enjoy the windows 8 user experience on a desktop, while windows 7 feels like a smooth relaxing ride. My choice is clear.
That's irrational unless you just really like transparency effects, more than actual features and usability. The Windows 8 desktop is a clear superset of the Windows 7 desktop.
I.. need to use my computer exactly the way you use yours. Yeah, that makes sense!
No, there are plenty of ways to use it, clicking on the start menu/screen is a) not effective (you have a keyboard, use it) and b) not something that most people do with any regularity anyway. (Telemetry data shows that people rarely use the start menu, since you can pin apps to the taskbar and just click on them there.)
Nearly all the complaints about Windows 8 amount to simply whinging about change. Mac OS X, iOS 7, Firefox Australis, the Office Ribbon, Ubuntu Unity - they all had loads of people complaining on release, regardless of any objective merits.
