So that's what's keeping Microsoft from just running WINE on an MS-flavored Linux or perhaps a clean slate kernel as their next OS. I've been wondering for a while, this is by far the best explanation.

It goes a little deeper than "does not care" though: worn out can also be a symptom of caring a lot. Caring in the way of having a strong desire to identify with the stuff worn, and newly bought stuff just not checking that box. Then any newly procured garb, no matter how carefully selected, perhaps even customized, will feel like being dressed up as someone else. It's like a trap, just not being wired for new clothes. I wonder if there's a connection to childhood dress-up play, as in kids who had good times masquerading as some archetype are less likely later in life to fall into that "that's-not-me" trap regarding new clothes.
