Agreed. Starts up fairly quickly but shuts down rather slowly; fairly stable but a little sticky when switching apps on the desktop (I have hung it up to the point where it's Big White Switch time). Best Windows release I've used so far.
Be careful about installing things that you're not going to use, which can be exploited, like IIS (standard disclaimer for all systems these days, but especially W32), and install a good anti-virus suite and firewall.
