So I've been using the final version of Windows Vista for 6 days now, there's one trend that really strikes me using this version.
Check out the Reliability and Performance Monitor:
Straight 10s, with previous builds on this computer this would often dip down somewhat as various applications crashed. So it's a good indication that the system is indeed solid as a rock. Before there would always be one application that would sometimes fail, usually COM Surrogate which appeared to have issues with an XviD codec I was using. Not anymore.
