But battery is about the only thing you can replace. If your trackpad or keyboard fails, you have to swap out the whole top assembly. If your camera or display cable goes, you have to replace the lid.

Part of that is unavoidable as laptops become ever more thin, but I am reasonably sure Apple could make the keyboard replaceable.

I recall on the older machines that they had upwards of 60 screws holding the keyboard into the top panel. I’ve not checked out a teardown in a long time, is that still the case or is it riveted in?

I always suspected that 60+ screw solution was very much over engineered but I guess they wanted to eliminate any potential for flex of any sort.
