In the middle of winter 2000, I was sent to Sun's "Super Training" campus in Broomfield, CO. It was a nice little campus and upon registration I was handed an access card that I could slot into any Sun Ray on the campus and access the same persistent desktop.
There were little clusters of Sun Rays all around the campus and I was very impressed with the system. It was nice to have a personal desktop environment I could customize and use for the 2 weeks that I was there.
