I really like this new os and haven't found a reason to go back to os2007 yet. My browser hasn't crashed yet and very stable. The only thing that has crashed was the app manager when installing pidgin. The lack of apps is the only reason I would go back but at this point the benefits outweigh the disadvantages.

BTW, Rhapsody is awesome. It hasn't crashed yet and the os2008 version has a few more added features like the applet, the album and artist page.
