Windows 8 download is here. Go get it.
And, while you are at it, get Windows 8 Server beta and a Visual Studio 11 beta.
[2012-03-01: I just finished installation and it cannot either install .NET Framework not it can do Windows Update. Somebody screwed-up something...]
P.S. And I still cannot run my own software without running through hoops since Windows 8 "protects me".
P.P.S. And, since my computer has no SLAC, Hyper-V as single reason for upgrade is there no more... :(
