I've been using the Gutsy Gibbon on my desktop for just over a week now. I pretty much settled into using it straight after the
upgrade fresh install from Feisty. So far I've experienced no real problems with it whatsoever.
During the past week I've managed to have a play with most of Ubuntu's new features. The one that has really stood out and impressed me the most has been the integrated desktop search provided by Deskbar Applet and Tracker.
