right..
Anyway, I personally loved Vista Ultimate. But it only worked on a high end PC. If you didn't have a fast enough CPU or enough ram Vista didn't run well. I built a new PC just for Vista and thought it was great. It was the first 64bit OS I used as my main OS. XP 64bit was incompatible with a lot of hardware and useless for a lot of software. But Vista 64bit supported both 64bit drivers and applications from XP, but was finally directly supported by hardware manufacturers for drivers. And unlike XP it could run most 32bit programs.
But for me the main reason for Vista 64bit was the support for more ram as I needed it for 3D and video post production software rendering for realtime previews. In something like Aftereffects, software rendering for realtime previews eats up a lot of ram. As does large photoshop projects. 3D and other programs from Adobe and Discreet/Autodesk too.
