Ok, good point. Thanks for the answer. The reason was just that I had a few minor problems. The computer seemed a bit more sluggish and also vlc, which I use to listen to mms streeming radio, died upon start. The latter is resolved however. I do not yet know if it's just imagination that the computer seems more sluggish but I will try to look into that and send a bug report to Ubuntu if I can find anything.
