It's been pretty much decided that we're staying with Windows2000 for awhile. At the school I work at, we've got at least half a dozen gaphics apps (modeling, compositing, rendering, etc.) installed. And students have at least 3 apps running at the same time (as well as web browsing and music listening). So yes, gotta make sure ALL apps play nice with each other. The only software that we can't use is Premiere Pro, which is XP only. (Still staying with version 6.) Oh yeah, a fellow tech updated his home machine which had a raid setup. Big crash. He's re-installing his system.
