Thanks for the suggestions, guys, but a new Mac is a down-the-road thought.
At the moment, I'm looking at the possibility of needing both a new mattress and a new desk chair, and my resources can be stretched only so far.
I'm not really ready for a new Mac other than to get rid of the touch bar, but it sure is an appealing thought.
(In addition, I may need to replace the keyboard and trackpad in my MBP to make it more salable, and that seems to be a major $$$ proposition.)
