Are we talking about this thing with a couple of MDP ports and some USB 3 ports?

With the 2.5 / 5 star ratings? Nah, that's not getting it done.
You might be right about it never supporting Thunderbolt 3; I don't know anything about MS' stance on it. What I do know is that their competitors in this price space and less have it, including products from:
Apple (obvious)
Asus
Razer
Alienware
Lenovo
HP
...and a few others that I can think of like MSI. They all have their pros and cons that I won't waste time on, but I don't have to instantly cross any of them off the list because of a lack of pro hardware support by design. It bothers me because I was briefly imagining this Surface replacing my MBP. I quickly had that notion dispelled upon reading the fine print. I generally have more confidence in MS as a brand than some of the others listed, so it would have been my #1 Windows laptop option if not for this.
It's fine for general use I'm sure. If your lifestyle generally revolves around Adobe products, MS Office and web browsing I'm sure it's good enough. But it lost a great deal of professional usage and longevity here. I would not be surprised to see a revision that updates the USB-C implementation at some point in the future. Ignore me, I'm just disappointed because it appears to be a lovely device and one that would have been on my very short list.
