Unless anyone hasn't tried, I finally got my install to work with Vbox. Guest additions don't work so it gimps the experience.
Not sure how I feel about the Metro stuff yet. I'm sure someone will find a way for it to boot directly to the desktop instead of the Metro UI. I know that for my work machines, I don't even want to see the Metro interface. I just want my desktop.
Looking forward to seeing what performance changes that have been made. I'd like my Windows installs to be faster, but hey, who doesn't?
