I used one for maybe a week at work a few years ago. Aimed it at my cubicle wall. Pros: - It was fun to try. - It sparked a conversation or two. Cons: - The size didn't really help; I'd say it got in the way more than anything. I had to scan more real estate to find what I was looking for. - It was more washed out than my monitors; lower contrast. Probably a function of the projector, the settings, the lighting, and me not knowing what I was doing. It would surely be better in a dark environment. - It was tricky to keep in focus. Any movement would make the projection fuzzy. It was a fun experiment, but the novelty wore off pretty quickly and I went back to monitors.
