It's also a major theme in the Steve Jobs biography that Steve was obsessed with this kind of aging in objects (evident, e.g., in his preference for faded blue jeans), and wanted the products he built to acquire character by scuffing, etc. (Not, of course, by actually degrading performance such as broken screens or cracks in the casing).

You may disagree with this philosophy, but the lazy refrain of "this wouldn't have happened if Steve still was around" is particularly clueless for this issue.
