I installed the Windows 8 Consumer Preview today. Set it up as dual boot on one of my Windows 7 desktops. So far it seems to work very well on that old piece of hardware. There was an issue with the network card but I found the floppy disk with the driver and all is well.

For those people experimenting with the Preview you can download a .exe file from StarDock to put a Start Button on the Windows 8 taskbar.

Installing the Visual Studio 11 beta on the system at this time.
