You make a very good point, but I'm not totally sure that it is the complete answer. I agree that it is clearly right for my browser to display pop-ups, and play videos, when I indicate my intent that it do so. My question was not whether that should happen, but whether any users want pop-ups as the method of interaction (or information display). Although I definitely want, in an operational sense, PeopleSoft to show me a pop-up when I click on the relevant button, because that's the only way to get to certain information, what I really want, in an aspirational sense, is for it to display the information in some other way, without a pop-up at all.
