I just upgraded to Ubuntu 9.10 on my laptop. It's truly amazing! The last version of Ubuntu didn't find all the drivers I needed, so some of my favorite webapps like Pandora and Grooveshark didn't work. The upgrade included all the drivers that were missing and my laptop now runs faster than ever!
Catalan language support is great too. All the menus and controls are translated well, which is something I've always wanted to do in order to help myself learn the language.
