Installed to separate partition so I didn't lose... you know... a working and efficient OS install.
Observations:
Win7 drivers work fine. Had to load drivers I downloaded for my KILLER NIC. Otherwise Win8 saw my hardware and made everything work right away, then windows update found stuff for my X-fi and creative webcam.
Desktop experience is.... well, it threw me for a second. Playing with it more is... interesting. Tablet interface with a traditional desktop underneath with modern game and technology support. Found that pressing the keyboard start menu button is a big alt-tab between metro (which has a big ol' START at the top, HAR HAR MICROSOFT) and the regular desktop or whatever's running. So I dub metro interface as nothing but a glorified and pretty fullscreen start menu, which... when you look at it that way, once it's figured out how to customize it, COULD be pretty nice. I would REALLY like to see animated backgrounds and/or animated shortcut icons for metro. Do that and I'll consider using it.
App store. Nothing special.
Mouse to top-left corner of screen brings what I think is the jump list? Or at least the last most accessed screens. Mouse to bottom-left corner of screen brings up clickable metro shortcut. Mouse to top-right corner brings up an overlay with start, search, share, devices and settings on the right side of the screen and current time and date in a small square on the left side.
Have dual monitors? Metro can/will automatically be running on primary while traditional desktop and taskbar are shown on the secondary. Kill metro or alt-tab from it to regular desktop and both screens will show the taskbar.
I don't see how to easily kill programs/screens/processes. I want to shut down this app store... uhh… app. How do I do that? Further with that, I don't see any blatant and immediate way to shut down your machine.
All for now, I guess.
Nevermind. To kill a screen that's a process in the background, bring up the jump list (top left corner of the primary monitor), put mouse cursor over it, right-click and get a single option. Close.
