For those who (hopefully) utilize their gear on a regular basis, if not on a work schedule, all the while neurotically caring for it's cosmetic condition as well, and anticipate an emergent necessity (G.A.S.) to trade-up to newer models or systems, original boxes and all attendant accoutrements therein will measurably increase the trade-in value of good and garbage alike. Mind you, I speak from the perspective of a poser and bum residing in the United heaven-Sakes of America. (That really big and famous store in NYC routinely asks about original boxes, paperwork, matching serial numbers etc when making trade-in estimates or evaluations towards the purchase of new, even newer used, gear.)
