I have a dual boot system Win7/Win8. The reason for dual boot is to be able to go back to many installed programs in Win7 in case there is a problem with Win8. So far (since Oct 26) there has been no need to do so.

Today I installed the latest version of Oracle VirtualBox in Win8 and its working well, internet, audio, etc. The really neat thing is that I could use my previous installed virtual WinXP by simply telling VirtualBox to use the original virtual hard disk file. It is set up with various old versions of IE and other browsers for website testing. Actually that is getting less important but it was really nice to not have to install a complete operating system with zillions of updates.
