Apple is
always working on new keyboards, of course. It’s just a question of when they’ll ship. Major keyboard redesigns coincide with major redesigns of the entire form factor, and those projects are on years-long time frames.
But of course the biggest issue with these keyboards is reliability. Will this updated mechanism fix or at least greatly reduce the number of reliability problems? Only time will tell, but I’m cautiously optimistic. […]
So on the keyboard front, these new models can’t be worse and are likely better. That’s good. The best that we could hope for while waiting for a true next-generation keyboard design — which for all we know might be a year or more out — is a mid-generation tweak. At the very least, talking about this material tweak and including all butterfly keyboard models in the service program is an acknowledgement that last year’s keyboards were not good enough. That was the worst case scenario — that Apple didn’t see a problem.
