For some reason, planned obsolescence causes me to "rage" more than it probably should.
"We warrant this product for 1 year because advanced statistical analysis of typical customer usage patterns, coupled with advances in materials science means that it is almost certain to fail within 1 week beyond 1 year of service."
Gone are the days of long warranty periods, or of expecting thing to last a long time beyond the expiration of the warranty period.
Though I'd love if there was a good way of analyzing the costs to society from using stuff that is a bit more expensive and lasts a long time vs constantly re-buying cheap crap that breaks quickly.
