Yesterday I just tried the update button in my Ubuntu update manager and I'm pleased to say the update to 7.04 Feisty Fawn went as smooth as it could be. No problems and Feisty Fawn seems to be running very smoothly now. Not that I had any problems before. It still amazes me how Linux has been improving over the past years. I can still remember all the pain I had when installing hardware and so on.
