It appears that some of you still don't get it. Would you like me to share a secret with you? (drum roll) dadadadada.......wait for it........wait for it.......here it comes.......This thread is a joke,the OP wasn't serious. Stick with your Windows 7,at least that is real.
Anyway, a "demo" version for win8 has available. It has few nice features but from win7 to win8, it is big change.
I don't think Windows 9 will be called "Windows 9", it will be something like Vista, with a different name.
