Vista is FINE.
It's just working through the kinks right now with it's mandatory paid beta testing crowd (everyone that bought a computer and wasn't given a choice on which OS to use) giving feedback (by whining to computer techs that the stuff they normally use isn't working) to their professional reps (the Indian guys you can't understand on the phone.. yea the same ones that can't speak engRish are the ones that are trying to compile bugs for the developers) so the information can be passed on their professional coders (the guys that have been working around the clock for the last 2 years trying to fix every bug, glitch and hiccup in Vista.. that usually causes every other bug, glitch and hiccup because their dev team and their troubleshooting team don't talk to each other) in order to be implemented (when and if there's a new windows update.. otherwise it may be lumped into a security patch.. but not likely this late in the game) As SOON as they can get the problem narrowed down and fixed.
See? Noooo worries!
