I recommend to anyone who wants to install Windows 8 to install it in VMware or Virtual Machine. You guys don't have to install it as a 2nd OS just to delete it later.
I haven't installed WIN8 yet but I already know it's going to be a waste of my time. You'll be handing over money for buggy versions like WIN Vistas and WIN 2k. Regular users should stay away for a while. On the backend - those "test" editions are more for the tech saavy types who don't mind debugging the hell out of it.
Web 2.0 is the new way technology is headed. WEB 2.0 try to understand it if you don't already. If the OS proves unpopular after coming out, then of course WIN9 is going to the drawing board for major revisions. Things work that way.
