I just returned my 15" MBP (stock, low-end 2016) after 13 days because I had numerous issues, including Touch Bar freezes, spontaneous reboots, and this lovely screen of colored static on multiple occasions (which doesn't appear to be listed as an issue or one that's fixed):

and also because of obvious places Apple didn't update the OS to realize the Touch Bar was there. Example from when I restored macOS prior to returning it (note how the user is asked to hit the Escape key for help... and yet the Escape key [and entire Touch Bar] isn't visible - and couldn't be make visible, at least in my attempts):

I hope this update fixed similar issues for others, but I've decided to wait until the next hardware rev before I buy a new 15". I ordered a base 2016 13" (no Touch Bar) cheap at Best Buy this weekend, and I'll use that for now... if I decide it's worth the risk to open it. This 15" was the first Mac I've ever returned after opening it. I'm really disappointed in the number of issues I had over a relatively short period of time using it doing pretty much nothing but software development. These were, in my opinion, pushed out of the factory way before they should have been.
I get that OS updates are needed and that new hardware isn't going to be perfectly supported all the time, but come on. It sounds like, even after this OS bump, there are still going to be a lot of people with issues, and I had far too many different problems on a new system that I barely stressed. I miss the old days when they really did just work.
