This is exactly the mindset Apple wants you to have and boy it is pure and utter BS. It does not matter one bit for quality, waterproofness or whatever if a device is screwed together, glued together or soldered together. You can buy a $200 Seiko dive watch that will let take your scuba gear down to 200m and it pulls apart into their individual pieces just fine with screws. But we can't make a splash resistent phone without glueing the thing together so it can never come apart again? Quit drinking the koolaid and sucking the Apple feeder tube.
Apple is actively trying to prevent repairs by trying to make sure devices cannot be taken apart without damage, by not allowing 3rd party repair shops to be able to make repairs, by not allowing the device to work with replacement parts that would work just fine, by pricing their own repairs so it is not economically viable to do them. And that has nothing to do with quality, waterproofness or whatever reason you can think of. It is just about money. About selling new devices. Apple does not want you to do 5 years with your phone. They don't want you to fix it after a year if it accidentally breaks so you can use it for another year. They want to sell you a new $1000+ device each and every year and throw the old one in the garbage. Preferably their garbage, so they can lowball you with a trade-in 'offer' so they can make money of your old phone as well your new one.
Its ok to make a profit. Money is not a dirty word. But not at the expensive of everything else. And that's exactly what Apple is doing.
EDIT: If Apple were a car company, it would be impossible to remove the wheels to replace the tires or change the oil. It would have amazing gas mileage that would let you drive halfway across the globe, but once it was empty, you'd have to buy a new car even if it's perfectly fine and would run for ages if you could just fill it up at the local gas station. But it won't, cause you it doesn't have a gas cap and you'd have to fill it up with Apple gas as it won't start on anything else and Apple gas is so expensive that together with taking it to the Apple store to have it stripped and filled it by them, it is just more economical to just buy a new car.
Oh, and you'd be convinced that in order to get great gas mileage a car shouldn't have a gas cap.
Last time I checked, my watch does not have a speaker and also not a port. Very weird comparison.
Waterproofness is one aspect, but not the sole aspect, which you would have noticed if you had read my post more carefully. Making devices thin is another one. Especially the screen is glued to the front plate to have no gap between the display and the surface, like in older devices.
To think Apple would actively make devices harder to repair is not a logical argument, because it costs them more too when they have to repair devices within warranty.
The truth is, it is just much easier to create a device that is thin and sleek with glue. Many other manufacturers have a comparably low repairability score, or in some cases even lower. Check out the note 20 here or microsofts surface devices here .
Your car analogy also shows that you have very limited understanding. IT IS the case that car technology becomes more integrated and cars are harder to repair / maintenance, partially because there is more technology packed into parts, engine miniaturisation, etc. You cannot nearly repair cars as much yourself as you used to. And yes, more and more you need to have your cars repaired by brand-specific repair shops rather than just your car repair shop around the corner, or at least they need to have proprietary parts and tools to maintain your car.
