For me, personally, Win8 is/was a disaster!
I dual booted for two weeks and tried hard to get used to it. It's just not for me on my desktop.
I can't really se the point of those tile things. I have similar things on my Win7 desktop - they are called shortcuts and are fully under my control.
If Microsoft were to release Win8 as an upgrade to Win7, at a reasonable price (£20 -£30) I might reconsider. But no way will I pay out £70 - £100 for it.
Looking at things logically, by the time Win7 support is withdrawn, I will probably be dead. So, long live Win7
