New release is out! I personally run Kubuntu, the KDE version. I upgraded from the previous version about a week ago to the release candidate. That update didn't go too well, but I got some very nice help in the #kubuntu irc channel on freenode.net and I got the problems fixed. The integrated sd-card reader in my Thinkpad Z61t still doesn't work which is a bit annoying, but I haven't really spent much time on it yet. I have hope that I will be able to get it to work. I haven't had much luck with my wireless adapter either. It does get detected, but for some reason I have problems getting it to connect to access points. That has not been that big a deal since (surprisingly) I haven't had the need. Since it is detected, I expect I should be able to get it working properly too.
Other than the problems mentioned above, I really like the new release. I think the (K)Ubuntu people have done a great job!
