People who don't like planned obsolescence when it comes to computing don't understand Moore's law. On the other hand, there is planned obsolescence in stuff like tennis shoes that makes less sense to me. I have to buy new tennis shoes every few months. And why do they call them tennis shoes? Most people these days don't play tennis. My feet stopped growing years ago. I have an uncle whose shoes seem to last forever. He's 65, I'm 28 and most of his shoes are older than me!
