I agree although have used laptops to take notes in meeting. But in hindsight, taking hand notes is less obstrusive. What about a tablet, which, incidentally, is terrible for taking notes?
In the larger world, smart phones, tablets or any digital device is a distraction when in the presence of company. And sorta rude...I am guilty of constantly checking my smart phone for e-mail, headlines and social media posts. That said, it's hard to imagine direct reports checking e-mail while the CEO or another C suite member is speaking. Bad form.
