I agree. I first try to keep my commitments down to a point where I can remember things. When I can't, I like the flexibility of pen and paper for jotting, scribbling, and sketching.

When I've run large meetings/reviews, I would walk around the room after things got underway to gauge how people were reacting to the discussions. The people with laptops would be working on unrelated material. Unfortunately, these would often be the senior reviewers.
