And also, something being a cash cow at the moment does not mean that thing will continue to be one. Since the iPhone 6ish, iPhones have become “good enough”; there’s not much to differentiate each model from the previous as there was with, say, the iPhones 3GS and 4. The iPhone 13 just doesn’t have much going for it compared to the 12.
There is no reason for them not to own the premium-business market with all day battery, but still powerful machines. Mac runs the office suite, Mac runs your browser and Teams, Zoom or whatever your organization uses. It runs figma, it runs your IDE, etc.
There are definitely areas where they don't work, and they don't really have a meaningful desktop, and some companies will have speciality software that isn't browser based.
But in general the boss-and-above market has very little reason to not use an Apple Air.
A Mini-chassis-based SE with a headphone jack and a touchID home button would be a day 0 buy for me -- I wouldn't even wait for reviews.
Unfortunately I think Apple's treating the headphone jack (on iOS devices) like USB-A, not like the SD card slot or the HDMI port (on the Mac) -- the backlash hasn't been strong enough for them to backtrack.
Of course, that leaves me trapped in the failed evolutionary path of my touchID, small-sized, headphone-jacked 2016 iPhone SE that's losing iOS support this fall. The Zenfone 9 has me intrigued as a modern SoC with solid cellular band coverage and most of the features I want. But it's still bigger than I'd like.
