Kinda the same here. We're running it on a few machines, and while the tablet-UI side of things is largely ignored, the rest of it works well enough. Yeah, there's some stuff that's missing (the GUI for modifying all stored wireless connections, for example), but I like the spatial nature of the new Start menu. It's kind of like being able to pin programs where you like them on your taskbar, but in two dimensions. Yes, I know you could do that with icons on the desktop, but you can't scroll the desktop, and you have to hide windows to get to it.
We don't have immediate plans to roll out Win 8 to everybody (as far as I know), but it sounds like there are some improvements to memory footprint. I'll have to test this in our ESX environment, because if we can reduce the memory usage of a hundred VMs vs. Windows XP or 7, then that might make it worth jumping over 7. If we take that route, I should be able to do a few hour-long lunch-and-learn sessions to get everybody up to speed. For most people, I'll just have to teach them about the Start menu. On the IT side, I'm sure we'd have to figure out what kind of new group policy settings would be needed, what with the app store and such.
