A potential problem for the used market is that, as people upgrade individual components, they are left with used individual components, which are potentially harder to sell than an entire laptop. And as, so far, the major component upgrades have been of the mainboards, it seems like there could be a glut of those, while it seems possible that a used chassis may never be easily available. As more component upgrades other than motherboards become available, however, it may be that a more useful used market could develop. And it may be that building a 'used' laptop may end up usually involving buying a few new parts. For example, having, over time, upgraded the top cover, hinges, mainboard, battery, wifi card, RAM, and SSD, if I upgrade the display and camera with the soon-to-be-available new modules, I think someone could build a full laptop with my old parts, a bottom cover kit, an input cover, and some fasteners; it may be that the bottom cover (and fasteners) are the only parts there that would need to be purchased new, as I expect other people have replaced input covers (some of my keycaps are starting to degrade, but they actually degrade rather gracefully) But still, this would be more complex than simply buying a used laptop, and would need a marketplace for all of those parts. I know there was some discussion from Framework hoping someday to facilitate a used component market; that seems like it would be challenging, but on the other hand, Framework seems to have been steadily, actually pursuing the goals they have laid out.
