Nope, it didn't come yet.
Why do you want to use Windows 8? It's as bad as Vista if not worse. Of course, I don't care if you use Windows 8, so go ahead and use it. I just think it's as bad as Vista, which is also what many people think.
i think you should investigate more about windows 8. windows 8 is such a lean and more efficient OS then vista (and even windows 7) in terms of how much resources it uses.
so i dont know why u would compare windows 8 with vista is beyond me. but i do agree with you that vista is a peice of crap. uses so much resources while running, making simple tasks all laggy.
but if you hate windows 8 because of the start button isn't there anymore, then i guess thats your habit. sure it is different finding things on windows 8. but "different" doesn't necessary be a hassle.
for example....when you do a certain task with "turning left" for 5 years. NOW you have to do the same task with "turning right". yes it will take a little bit getting used to. but you're only making one single motion to complete your task.
im currently has been using windows 8 ever since it came out. and i love it. everything is so much snappier and quicker then windows 7 *not even gonna mention slow-azz vista* the quick start-up and shut-down is enough for me to pick windows 8.
