repairability is a huge point in luxury products. the fact that it very easy to get a luxury watch or a luxury car serviced is a part of it.
watches for example are marked as heirlooms to be passed down across the generations, and as one it is meant to stay in good condition for a long time. Rolls Royce takes pride in the fact that 65% of all cars they ever made are still on the road. for a product to withstand such a lengthy amount of time it must be easily serviceable.
the problem with tech products is that they get outdated after a (relatively) short amount of time, so servicing them for a long time becomes unprofitable.
the situation with other manufacturers is much worse, I had a comparatively amazing experience with apple
I will address your concerns in regard to both mobile and computer repairability:
repairability of mobiles - this is a universal problem - mobile phones have to be so portable that when you don’t use them you don’t even notice they’re here - that means that you have to pack as many components as possible in the least amount of space possible - that means that a lot of times components will be not only glued soldered together, but will actually be part of the same integrate circuit, to save space. this is universal - most phones receive a score of 4, only a few receive a higher than that, and they are mostly niche devices where this is the part of their premise. the reason iPhones do not receive a repairability score of 7 is because of the software lockdown, where apple limits the functionality of non-verified parts. I actually believe apple handles the software lockdown in a way that maintains a good balance between privacy and right to repair, where if a non-verified component is recognized, the user gets a notification and features related to that component that could have an impact on the users privacy are disabled.
repairability of computers - it’s true indeed that in the days of the intel “all-flash architecture” MacBooks repairability was abysmal because apple chose form over function - and you can see that best in the trash can Mac Pro where components that should have been upgradable we’re soldered to maintain the sleek and compact form factor. since then apple listened to it’s customers and today the situation is very different.
a lot of the reparability issues of the Mac lineup stems from the use of apple silicon - the apple silicon has what they call a unified memory architecture which basically demands that the RAM will be a part of the SOC’s integrated circuit, that’s true for even the Mac Pro which is extremely modular. the storage indeed soldered on the motherboard for laptops and Mac mini in order to save space, but for the Mac Studio and Mac Pro the storage is removable. other than that - overall all the Mac lineup is quite modular and easy to repair hardware wise but the software lockdown issue exists here as well.
overall, even if the move towards repairability was forced on apple by legislator, I still think it’s a move I the right direction and will allow for cheaper and quicker repairs as apple moves towards in-store repairs instead of replacements and allows 3rd parties and personal users to order genuine parts and repair manuals.
