Actually, it's not always perfect. Twice Microsoft has pushed updates through to Vista that have resulted in a loss of sound. Once a year ago, once two days ago (but an old update, I'd not update for a while
). Uninstalling the update restored the sound instantly.
And yet, this is absolutely the only problem I have EVER had with Vista. I know it gets a bad rap (with good reason) and people have been told to avoid it ever since MS announced they would release 7 soon, but I've had no other trouble for three years now.
Better not jinx it now...
