During a meeting in Sydney, Twitter founder and CEO Jack Dorsey answered a question about Facebook founder Mark Zuckerberg's famous photo showing scotch tape on the computer camera. Dorsey said:
I don't have a laptop. I do everything with my smartphone. This is important to me, because I turn off notifications and use one application at a time. I only have one app open, and I can really focus on what's in front of me instead of all the things that would come to me if I used a laptop.
Dorsey then explained that he doesn't type much, but that he mostly dictates the things he wants to write, and that to save time he doesn't check his phone in the morning until he's about to go into work. During meetings, it requires laptops to remain closed and phones face down, so as not to get distracted.
