Eugenia Loli-Queru of OSNews published a review on Ubuntu Gutsy Gibson

As far as new features go, you will find there everything that comes with Gnome 2.20, the nice Tracker tool for indexed searches (feels faster and lighter than Beagle), a brand new Bluetooth panel that supports several profiles, a better Compiz, a dual screen setup utility, and voila! After having several reviewers whining about it, laptop trackpad properties in the mouse panel! However, what strikes you the most is the amount of polish that has been going on in the last few months on the existing tools. Everything just feels more professional, more stable, more good looking, heck, even more HIG-compliant. I like what I see and I hope more people take notice too.

Ubuntu: One More Release, Yet More Polish
