As someone who worked before there were smartphones--indeed, before there were mainstream cellphones and laptops--I'm acutely aware of just how "chained to your desk" you used to be in that, if you weren't there, you couldn't be reached. Of course, you were sometimes in meetings. But, for the most part, you really needed to be sitting at your desk most of the day if only because someone might call you with a question. (Yes, a sales rep calling me on the phone as a product manager was the norm.)
