Pros wanted HDMI.
Every office conference room has a projector. They all have HDMI. Seriously, good luck finding a projector with DisplayPort. Bringing dongles along is a pain. Yes, dongles work, and they’re great on a desk, but it’s a lousy solution for running around the office.
I’ve been to countless business meetings with my USB-only Mac’s, and these dongles don’t look professional and they don’t convey Apple’s sleek, cutting-edge image. A MacBook Pro on a conference table with a bunch of cables hanging off a dongle looks awful.
