I had my first snafu with Vista. It seems that if I allow my computer to standby at all, when I resume from standby, I lose my resolution and it defaults to 800 x 600.
Overall, I have been quite pleased with Vista's performance. I have a laptop (aero glass capable) with 2 GB of memory and I plugged in a 2 GB flash drive for a boost to my performance. What a great feature!
I also loaded Virtual Server Beta 2 and I did a Physical to Virtual image of several of my main computers. I now have the ability to run Vista as the Host OS and several other desktop configurations including Red Hat Linux on my Vista machine through the use of virtualization.
More to come...
