Sure, that is great, but even with prior generations of MacBooks dongles were a hinderance. I'd end up at the end of a conference with at least a couple mini-Displayport to VGA adapters from people who were presenting but forgot them for one reason or another, and I'd usually only be able to get 2/3rds of said dongles back to their rightful owners.

With USB C at least for now, this will be a constant source of fustration for users who don't own a Google Pixel and have to deal with legacy hardware (everything else out on the market). That being said, USB C itself is great, Apple should adopt it on the iPhone.
