I think Apple being as big, and making the big technological leap with M1 convinced a lot of customers to buy the new Macs. Even those that technically weren’t needing one/upgrade. Now, that curiosity bubble has saturated with the M2 being an iterative improvement and the customer base certainly not as desperate (intel to M1). Given enough time, I think the Macs will continue to gain market share. Most tech companies…
This makes sense. Amongst my friends, a number of them maxed out an M1 machine not just because of the processor but also because of the improved I/O and new form factor. The M1 machine ticked so many boxes that the purchase decision was not solely pushed by the CPU. The machines are so good it’s hard to justify a new one!
I imagine Apple will have to accelerate planned obsolescence (maybe dropping from 7 to 5 years of OS and security updates) to make analysts happy. ;-/
More seriously, I've gotten 7+ years of use out of multiple Apple devices. Though my 2014 iPad Air 2 is probably going to be retired from the internet once iPadOS 15 security updates end.
Also I expect a minor boost for Apple if Apple Silicon based Mac Pro machines (and perhaps pro iMac models?) turn out well.
