So far I have been pleasantly surprised with my Vista install, a few things needed upgrading but no show stoppers. At least not until I copied a file from the media center machine. I was getting only a few mb/s despite the fact that both machines are connected via gigabit ethernet and have striped raid arrays. It only seemed to occur when playing audio…any audio, regardless of source. This wasn’t good at all.
