For someone like me who travels and digital nomads, the 14” MacBook Pro is perfect. iPad is definitely not in my interests but while I definitely can be more productive with more displays, I surprised myself how quickly I got used to using just the MacBook screen.
It's stupid to say this, but I think I work better with just one screen. The temptation to put Slack and email on the second screen and have too many things going on at once is too great. Using a single screen (the MBP display) makes it easier to focus.
