People never trusted Windows XP when it came out. Why have a slower Windows 2000 with nothing but security issues?
That’s the way it is with Vista today IMHO. But things move on, everybody with AE will want to utilize at least 4GB and sooner than later, 8GB of RAM. Vista will improve and get more support and apps to work on it and will be the tool for everyone, from high end animation artists such as ourselves to kids playing their latest High def 3D game.
And then I guess everyone will ridicule the next MS OS. And Adobe, as always, will keep on making wonderfull tools and taking their sweet time to fix the bugs. I still have a first red frame when importing HDV on all Adobe apps.
