That's what Apple wants you to think.
In some respects, the 13" pro is actually
inferior to the Air. It has no magsafe/worse IO, smaller screen, worse webcam, thicker design without any extra expandability to come along with it. Same chip/SOC and no ability to support additional monitors above what the Air can already provide.
You do get a fan, better speakers, touchbar, and slightly better battery life. The fan is not a negligible benefit, and is what really sets this machine apart from the Air lineup for a lot of people.
