Laptop sleep and hibernate work under Ubuntu out-of -the-box on my Dell C640. Also there’s this nice little update app that negates the need to type “apt-get update && apt-get upgrade”. It’s a nice little GUI that works.
I’ve also been using Muine instead of Rhythmbox to play my Ogg Vorbis collection. It’s a really nice app with a very simple but clean and effective UI.
It also looks like the Ubuntu people are picking up the NetworkManager technology that I like in Fedora. I’ve also had two patches acceted into the Gnome 2.10 release of Metacity. They’re trivial patches, but it’s a start. I intend to do more Metacity hacking in the future, the codebase is remarkably clean and easy to understand.
I think I’ll be sticking with Ubuntu for a while. I really like Fedora but the availability of Mono, Evince and proper laptop suspend support on Ubuntu are killer features for me.
