release candidate for windows 7

so i've upgraded a few systems to the release candidate in the past week and tuesday it is available to anyone.  the installation (or upgrade) from usb stick has been fast and flawless.  the first install was upgrading from interim build 7077 to the official release candidate (build 7100).  the second install was an upgrade from windows vista sp2 rc to windows 7 rc.  the third installation was a fresh installation.
