Vista 64 has been running well on the MBP. However, once I hooked up and configured the computer for the 24" ACD, I have no brightness control on the ACD. I can move the brightness adjustment scale, but the brightness does not change. This is only with the ACD, the brightness adjustment on the MBP screen works fine. Any Ideas? I'm thinking the bootcamp driver for the ACD is not quite up to snuff yet? One another note about the 24" ACD, if I keep the lid closed on the MBP, after a few minutes I lose internet connectivity. This happens in OS X as well as Windows, very strange.
