I think I probably played with it at my job on my early model IBM PC/XT since evaluation was one of my jobs. But I also had a Lisa on my desk for a while, which was much better (but insanely expensive). PCs back then were just not powerful enough to do much in the way of a graphics UI. Visi On was ahead of its time but way too far. Most people were using DOS based UI which wasn't bitmapped and was mostly fine for the time. Even Windows wasn't all that great until 3.0. Today we take for granted how ridiculously more powerful everything is.
