So USB-C is what it takes to get you to switch to Linux? What are you going to do when all other laptop manufacturers follow suit - switch back? Mac users who make this threat sound just like people who threaten to move to Canada every election cycle.
Personally, USB-C is the least of my problem. I care about having a fast, powerful laptop with 32 or 64GB ram (I run a lot of VMs for my work, I could offload it to the cloud but then it's more of a hassle). I complain because Apple decided to make the macbook pro 15 inch lighter and thinner resulting in 25% less battery (going from 99.5 watt-hour to 76.0-watt-hour), this means that they have to make more compromises…
Once the next generation of Intel processors land, I bet we'll see Macbook Pros with faster processors and 32GB or more of RAM. At that point they will catch up to their competitors.
But it's important to remember who Apple considers their competitors. They've never competed on the cheap end--everyone knows that--but they've also never competed on the high-power end. For at least the past 8 years it's been possible to buy laptops that deliver more horsepower than a Macbook Pro, by caring less about size, weight, and battery life. I think that will always be true.
