Some people apparently believe that computers become slower as they age. They believe that the older the computer, the longer it will take to boot, and the longer it will take to start userland programs. The commonly offered "solution" is to do a "factory reset" of the computer, or to replace the computer with a new computer.
My computer has run on Ubuntu for nearly 6 years now, and I do not notice any slowdown. It is just as fast as when I bought it.
Is there any truth to the belief that computers become slower as they age? Is it just a Microsoft Windows thing?
