The rumors are flying and supposedly today is the day for Vista Service Pack 1. This update, which the rumors say will be available for manual download only, should fix a plethora of problems that have plagued the Operating System for a very long time.
I'm not sure if the rumors are true, but if you are using Vista, it's definitely worth checking out.
As for me? I'll use Vista as soon as I can't get my hands on a copy of XP Pro, thank you very much.
