I think the laptop misuse in a meeting is a symptom of an unfocused meeting with too many of the wrong people invited. Meetings should accomplish work, and the right people should be at them to accomplish that work. We have a database interface set up specifically to facilitate meetings, with lists of ongoing projects, and the ability to actually put notes against tasks, add budget items, assign people to tasks right there, send correspondence to concerned parties, etc. It is all designed to work on a projection monitor. It works for us. I think it helps to reexamine what meetings are even for, and design systems toward that end.
