Impressed by openSUSE 10.3
So I replaced Kubuntu with openSUSE 10.3. All I can say is wow. I couldn't follow its development as I did with previous releases and tested only after the final version appeared. First I upgraded my desktop from 10.2 and it wasn't a pleasure as it made the system unbootable and I had to fix using a rescue console. But after having it running I was quite satisfied with it.
Software management has improved (but still not fast enough in my opinion), the possibility to add the community repositories from YaST is nice, as it is the search page and the one click install (well one click on the webpage, several clicks later). I found some bugs and annoyances and I reported them, in the hope that they will be fixed in an update or in future releases.
