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.
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.
