Some of the changes are actually pretty good. The hover-over title bar on Metro Apps seems like a no-brainer. The hover-over, universal task bar for easy app switching is also a really good idea. Right-clicking works now on the Start Screen... where have you been?
I mean, it's real easy to see these things in hindsight, but you gotta wonder whether anyone in Microsoft was testing this out on desktops with large screens, and didn't reflexively hit the right-button and expect something to appear. I mean, the developers didn't create Metro on small-screen touchpads, did they? Someone over there must have noticed how awkward and strange it is to work modern apps on a workstation, right?
Don't know whether to give Microsoft credit or slap them. If these features had been in the original Windows 8, there would have been a lot less hate (read: a lot more adoption) of the operating system on the desktop, and maybe an easier path for people to jump off XP. It's the arrogance, the suck-it-up, get-used-to-it, and the desktop-is-history BS that turned me off so hard, with a blatant disregard for just plain stupid things, like switching out of the desktop to some lame Metro previewer each time a user opens a PDF file (with no visible way of getting back).
These changes, plus the promised Start menu in an upcoming release, might just make Windows 8 usable in the workplace like 7 is. In view of that, I hope Microsoft has turned a corner, 'cause like it or not most people (me included) depend on Windows to make a living. Hopefully, they understand that again, and will keep throwing bones out to us desktop users (maybe permit more desktop customization features? fix those ugly window decorations? drop shadows?). But they wasted almost 2 years in the doghouse alienating their biggest customer base, and encouraging people not to migrate off XP and older systems. Hope their learning their lesson.
