That just sounds like common sense to me. Why replace a washing machine that still works just fine? For some gimmicky features or a shiny modern industrial design?
I fall firmly in the camp of not replacing stuff that works, clothes that still fit and aren't worn out, anything that still serves its purpose. Obviously I will repair or modify things to the extent of my skills to keep them going, clothes and computers are what I'm best at.
My TV is a 42" LG LCD that I picked up for $20 ages ago when my company was moving to a new office building. It works perfectly, supports 1080p and the picture quality is good after the usual adjustments I would have to do on a new TV anyway. None of the new TVs I can buy offer any real tangible improvements that make them worth the additional cost.
Sure, when this TV eventually breaks, I'll probably replace it with one that's slightly larger, 50-55" would be ideal for the space I have on the wall. But there's no need to rush that upgrade.
Consumerism has broken people's brains, they're stuck in an eternal loop of trying to keep up with the Joneses, never happy with what they already have. It's unhealthy and wasteful.
