I just upgraded to the new version. As with the last release, the operating system is integrated with the net, with a repository of 30,000 free software packages (one click install), and 2GB of free cloud storage.
Also, I like the integrated music store in the RhythmBox media player, where people can either purchase music, or artists can submit music. There's two music hosting services for artists: Jamendo (where music is essentially submitted as free/public domain), and Magnatune (with traditional music rights going to the artist).
Also, I'm happy with WINE (windows emulator) where I can run my older Windows applications, like Macromedia Flash 5. It's still a little hit-and-miss on the most recent Windows applications (where the emulator hasn't caught up) but I've found it runs older Windows programs better than Windows. I popped in an old Windows 95 game the other day, and it ran flawlessly.
