I'm just waiting for the shutdowns to start every 2 hours, then I'll be installing Fedora 12 (scheduled release - Nov 2009) on the machine which I used for testing the beta and RC. I still can't get over the way you can't tell which folders are shared by just looking (sorry, no - I don't care to float the cursor over each folder one at a time), and the way the desktop manager shuts off every time an Aero-unaware program starts, making you run and step through the troubleshooter to re-enable it. et cetera.
Being able to run a virtual XP is not that attractive. The only program without a linux version that I care anything about is AutoCAD, so hopefully AutoDesk will wise up and get moving on a pure POSIX release and I can eliminate using WINE for that, too. SE-Linux still appears to have a better handle on security than windows, though 7 is an improvement (and I do like it better than vista).
