The distinction is really important. This means that Dell for example is already at this metric, as all their laptops are opened with a few screws and their repair tech just swaps boards and sends the old one for RMA. But in practice this also means that given parts availability, the devices can be successfully fixed by consumers. as an IT guy who worked in a lab full of dell laptops, i sometimes did the odd repair and dell would just send me the part overnight, i'd swap the part and put the old one in the box and a courrier would pick it up day of. Say what you will about the quality of their computers, but their repair program is extremely efficient for the consumer, and because they won't spend too much money training proximity technicians, they engineer their products to be easily fixable.
