Yes there is a reason. This device is meant to be ultra portable and mostly used wirelessly. If you need all those ports get a rMBP. That's Apple's thinking IMO.
Exactly.
I have a rMB, it is my work computer. It gets used for Preview with PDF docs, Mail, and Word. It has NEVER had any peripherals plugged into it. The size and battery life far outweighs my need for ports in that use case.
For my personal use, it's rMBP for sure, but I'm ok with the weight and size there as it doesn't go from meeting room, to meeting room, to meeting room on battery.
I have the OWC Thunderbolt 2 dock for my rMBP, so even there I'd be OK with one TB and maybe 1 USB. Right now at my desk at home I plug in power, one TB cable, and I get the following:
- Ethernet
- 4 USB 3.0 ports
- Audio in / out
- FW800
- HDMI Display
- Thunderbolt Port
- SD reader (would have been way better if it was a UHS-3 reader though)
It's only a matter of time before someone makes a rMB dock that makes it so that one USB-C port becomes:
- Ethernet
- Audio
- HDMI
- Thunderbolt
- 4 or 5 USB
- SD Card reader
Once that happens, it'll be the perfect work computer, plug in at your desk and get all your goodies including a second display with only one cord!
Back to the topic at hand though, that hinge on the LG sure is ugly and I'd be worried about it collecting debris. The MacBook is beautifully simple. It doesn't need a "watch hinge"

It's not a masses problem that needs solving. Until this came up, I don't recall ever seeing anyone griping about the headphone jack itself.
Working at the Genius Bar, it's amazing how many times people came in with headphone plugs broken off inside their headphone jacks. It was a very common occurrence, especially with crappy headphones. I never saw a lightning cable broken in the socket though.
Admittedly not a super common reason to switch, nor is audio quality unless we plan on having DACs in the headphones along with Apple upgrading everyone's Apple Music or iTunes Match files to ALAC.
I don't see the 1/8" jack being obsoleted, but supplanted by the option of lightning headphones. Who knows though, maybe Apple will start shipping a phone without 1/8" and throw in an adapter.
Lightning headphones could enable some crazy tech like HR monitors, thermometers, or pulse oximeters in earbuds for when working out!
