I don't particularly care about repairability for $99 things, but that also means that I'm agnostic: in a vacuum, repairability is always better than the alternative. Unless there's actually an engineering reason for not allowing it, of course.
But I think expectations are at issue here, and that's creeped in the wrong direction. For instance, if I were going to buy the next iteration of whatever the Mac desktop computer is, I'd want user-replaceable SDDs and RAM. But I doubt that's happening. If it's a new MacBook Air, I think I'm conditioned at this point to treating the thing as vacuum-sealed and only repairable with special tools or at a repair shop.
That's not particularly great. Hell, my main computer is an OG MacBook that I've replaced the HDD with a SDD, upgraded the RAM, and swapped a new battery in.
I'd personally love for the Pro line of things to have user-swappable parts, but that's because I care less about an extra few millimeters saved on thickness. Granted, it won't prevent me from upgrading this thing to the next M1-chipped MacBook Pro in a few years, but I also know that if I want something customizable, I've got to go elsewhere.
