I don't understand why MS didn't allow Windows 7 to mature more. Look how well Windows XP did all those years! From an IT standpoint having a major release like Windows 8 not 3 years after Windows 7 was released is a logistical nightmare. I know companies who are still just now releasing Windows 7 into their corporate environments.
I haven't had a chance to play with it but I hope MS fixes the issues with creating Windows 8 images that was such a pain in the ass to do with Windows 7. Sysprep broke a lot of customized settings in Windows 7.
It now is rumored that Win8's successor may be out in 6 months. Vista de ja vu... It might be free or minimal charge to Win8 users....
