Ubuntu Karmic Koala is out for a bit. I've been running it for a week on my Aspire One netbook and so far have only good impressions.
The distribution upgrade went smoothly. I'm not surprised. Its Debian genes show reliability of upgrades. Yes, there were reports of upgrade problems on the interwebs, but so far as I understand they were related to binary blobs, i.e. closed source drivers and such, which is not surprising - it is hard to figure out whose responsibility it is to make them work properly - the infrastructure of a linux distro is very different from that of Windows or Mac OS X. It is unclear whose job it is to do trigger the updates if they were not handled by the default install in the first place - it is a very murky territory usability wise. But that is becoming a rather off-topic rant.
