Just to reiterate, we all do this except me, because I don't have one, but I notice this a lot at various committees, not just this one. The witnesses come in, and within about five minutes a fair number of us have our heads down playing with our BlackBerrys. To show deference to the witnesses, I think we should put them down, put them away or turn them off, at least during the presentation. I actually find it quite rude.
My own colleagues are just as guilty of this as anybody else. Someone is presenting, and within two or three minutes they're on their BlackBerrys and are not even paying attention to a person who has travelled all this distance to come here and make a bilingual presentation on a serious issue. As a courtesy, to show that we're actually listening as parliamentarians during the presentation--and we don't have to make this a motion--we should turn them off or pay no attention to them until after the presentation.
