I finally got around to installing the Beta release of Windows 7. Did the first install into a VM (virtual machine), just to get the feel for the new OS. I installed a copy of Sun xVM VirtualBox, version 2.2.2, which has predefined settings for a Windows 7 environment. I then loaded the Windows 7 image file as a DVD drive and got the install going. The install went smooth and the interface looked quite a bit like Windows Vista.
I will work with the VM installation while I assemble a non-production test system. I'll keep you updated on my adventures.
