Also why not introduce a new keyboard with a touch bar for all other desktop macs so every user who wants to use the touch capabilities would do so on the millions of desktop macs out there.
This would transform how people do things rather abruptly and make it so that older hardware can get access to the newer features of software and newer services like Apple Pay.
And why not intro a new bigger track pad with the newer tech.
Both of those things would show a certain amount of understanding of what their customers would want and need.
Hopefully in time those things will become available.
