How often do people need all of them when mobile, though?
That was what bugged me about my 2015, I'd get to my desk:
- plug in power
- plug in external monitor 1
- plug in external monitor 2
- plug in headphone/speakers
- plug in usb for hub with drives
- plug in usb for keyboard/mouse
With my 2018, I get to my desk:
- plug in single USB-C to dock with everything else already plugged in
Where the extra ports come in handy is when I'm AWAY from my desk, and that's when having ports that actually match the things I'm going to plug into them makes sense.
