I've used Windows 8, I am using it now on my NetBook, its very poor, a) metro-apps aren't supported, b) I get 'limited connection' displayed when I re-open it meaning I have to reboot all the time.
Unfortunately, the general populace are sheep, Windows 8 will be a success amongst the general populace and soon accepted. Just look at the PR behind IE9, that song from the adverts went straight into the UK Top 10 (and probably elsewhere). People are easily suckered.
