I have it running on 3 user's PCs at the office, and my desktop and laptop at home.

Have a Server 2012 Server running in production as well.

I think the UI is a little awkward on a non-tablet, but it's also not remotely as bad as some reviewers/bloggers made it out to be.

Performance is good.

Had a few business applications that wouldn't install right away, but there were ways around that on all of them. One odd one was that Win8 ships with the proper version of .net, so Windows Update won't load it up, but it has to be enabled from the command line because the installer for the app didn't know what to do with that.

I have Office 2013 preview on the desktop at home, that's a little bumpier at this point.
