The touchbar was both crappy ergonomics/ux (you have to look down at your keyboard to use it) and so isolated that there was never going to be significant developer investment - only on the macbook pros, and only useful even on those machines when not in the clamshell mode most people use the machines in when docked at a desk. It was never available on the airs, imacs, minis, or mps.My wish for the next MBP is less cost to the RAM and SSD upgrades. Which is unlikely. <sigh> The huge cost of RAM upgrading in particular causes me to add two years or more to my MBP life cycle planning.
Magsafe, though nice, is not the huge value add it was originally when it replaced a connection that broke cables and routinely helped pull laptops to the floor back when we needed to be charging almost constantly. Today we only need to be plugged in to charge once a day and can easily do it in a safe location, usually while the whole household is sleeping
Also, many of us who learned to use the touchbar liked the touchbar a lot. Hardly an "abomination." Personally, I am equally OK with having a touch bar or not having a touch bar.
If they really had wanted developer investment they would have added it to the external keyboards as well.
It was a doomed gimmick from the minute it arrived. Peak Ives form over function, especially when paired with unreliable keyboards
