Yup. My MBP at work: one thunderbolt port for an external monitor, the other for ethernet. One USB port for my nice keyboard, the other free. And the magsafe for charging. So I'm currently using 4 of 5 connections, and the new MBP will only have 3?
So now you can plug a single cable in and get power, display, and accessories. Where's the problem?
I'm guessing people don't upgrade their TVs, monitors, and projectors as often as they upgrade their laptops. I can't even find a USB-C adapter that would work with my current display (which was made by Apple)
You'll be able to use a single thunderbolt 3 port to get power, monitor, ethernet, and USB accessories, sit down, plug one cable in and you're off to the races.
