I finally got around to downloading the ISO. Screenshots below. I really like the Metro tile interface, but it is a bit jarring when you switch back to the classic display for common functions. Hopefully this will be smoother before RTM. Also, the offering of Hyper-V for virtualization was an exciting feature to see listed. That was a big wish list item for many people on Windows 7. IIS appears to be the same and I would expect SharePoint to run on Win8 no differently that how you can run it on Win7 today.
