Controversial and snarky take:
I think macOS is going to transform more and more into iOS, and not in a good way…losing all the advantages of a keyboard and mouse driven interface. The lowest common denominator with lesser Apple developer effort will win over.
The work on this machine also possibly explains why Apple has not spent any time improving its own Catalyst apps like Reminders, Notes and others on the Mac. These apps ported from iOS do not understand keyboard navigation and rely heavily on the trackpad or mouse. With the introduction of this machine, Apple has no (financial) reason to improve these apps anymore.
