Linux: Kubuntu 7.10 Released!
According the the upgrade site, Ubuntu/Kubuntu have been released as of today!
I'm really looking forward to the much-anticipated new version. 7.10, or Gutsy Gibbon, promises a 3-D desktop, a new version of KDE and the native ability to read and write NTFS drives. There's also a new video control panel that's supposed to make hand-editing config files a thing of the past.
Here's the official word on how to upgrade: http://www.ubuntu.com/getubuntu/upgrading
Let me know how your upgrade goes (if you're in the club;). I'll post again when I've finished my upgrade.
Update: Well, the suggested upgrade path (using Adept) didn't work. I'm now downloading the alternate CD for 7.10 and will try an upgrade from that...

Despite all the trouble, I'm very pleased with 7.10.
