Now put yourself in the place of the meeting planner/organiser. Because that's often you as well. If you're a project manager or in a PM-related role, then you've called and will continue to call your fair share of meetings. Do you want this to be your attendees' feelings toward your meetings? Do you want them to be feigning participation while they are really working and thinking of ways to get up and leave? Definitely not...and it can be distracting to you as the facilitator to look around the room and see people typing away on laptops, not making any eye contact, or texting on their iPhones. Productivity down the drain.
