I just switched from Ubuntu 7.10 - Gutsy Gibbon to Ubuntu 9.04 - Jaunty Jackalope.
wow! I am really impressed! Jaunty really looks solid. GNOME 2.26.1 is just awesome! Everything looks tightly integrated and working!
Thanks and congrats to the Ubuntu team and GNOME team for a solid release.
Ubuntu 7.10 Gutsy Gibbon reached end of life on 18th of this month, which forced me to do this switch. After installing Jaunty, I am very happy that I switched!
RIP Gutsy Gibbon, and welcome Jaunty Jackalope.
