I'm in the process of upgrading my laptop to Windows Vista beta 2 and Office 2007 beta 2. Since I do all my development in VirtualPC mode, my first step will be to determine how well my VirtualPC images run on Vista.
I love the way the Vista Enterprise site provides the reader with an example of using Virtual PC Express:
"With Virtual PC Express, you can conveniently run two operating systems on a single computer through a virtual machine. While the latest operating system version (Microsoft Windows Vista Enterprise, for example) runs as a host, the other operating system (Microsoft Windows XP Professional, for example) runs as a guest in the virtual machine."
Well I'll be giving it a try.
Btw. for downloading Vista, WinFx and more, go to: http://msdn.microsoft.com/windowsvista/downloads/products/getthebeta/
