I like Windows 8 under-the-hood. ClassicShell is an awesome start menu replacement, since you can select several different styles, and makes it much easier to shut the computer down. I can see how the Start8 tiles would be nice for a tablet, but it's really not great for a desktop. So I like some of the new features of Windows 8, and looking forward to Storage Spaces, but would prefer it to look like Windows 7 (but with a Windows 2000 start-menu!)
I get he impression that Windows 8 is 2 OSes. A tablet OS to run Tablet apps, and a regalar desktop OS. There are too many things about the tablet part of it that suck when using a mouse. For example, if I launch the news App, it is a pain to get back to the Metro start window again. I have to hover the mouse near the bottom left corner, and wait for the Start icon to appear. It usually take many tries for the icon to come up so I can get back to the start screen. The Metro Email app sucks as well. Their are no checkboxes for multi-delete, and the trash icon is way across the screen. You have to use the keyboard DEL key to get rid of messages in a timely manner. I went to the camera App, and again, the shortcut to go back to the Start menu didn't appear aqt the lower left, so the only way out was to switch out of the app. That's fine for a tablet, but not for the desktop.
Maybe I only have to see the Metro stuff for 5 seconds, but I'd really prefer not to see it at all, on systems without a touchscreen.
