I'm going to stick with my original line, you're all grossly overestimating the intelligence of the average users out there.
I like some things about Windows 8, I dislike some other things. As I don't directly use the start menu that much (although I think I now use it more than I used it oddly enough) it doesn't really interfere with my PC environment too much. I almost certainly wouldn't have taken the jump to it if I hadn't been build a new PC and been able to get it for 15 quids.
However I think it's a excellent touchscreen interface and, as touchscreen laptops become the norm like the
Asus Vivobook thingy I was playing with last night (nice but still ever so slightly expensive), Windows 8 will start to seep into the general consciousness of the average buyers/users who will
never delve beyond Metro.
