Great roundup... yeah, i'm not really feeling the update after having thought on it more. At first, I just wasn't sure. I thought the touch bar was interesting but mostly felt like a gimmicky addition. But the real crime here is in the specs... Apple has for years shown less and less interest in putting top of the line components in its pro models... but this year is among the worst offenders. A huge price hike with middling improvements in the ways that really matter: more ram, faster chips, being forward thinking on things such as VR. All things you can get in windows laptops that, amazingly, cost HALF as much or less and have improved in their external designs quite a lot in recent years.
If you want a pro-grade laptop that looks nice, really check out the new offerings from Razer... I think they are starting to get really serious about taking over this market. And maybe they will, since Apple clear doesn't care.

Also, Thinkpads, and some of the nicer Dells like the XPS line.
