"Is it specifically planned obsolescence, or just case of technology evolving? " It is not a coincidence that "technology evolving" results in obsolescence. It is true that it is additional effort to support old devices, but it is a finite and feasible amount of effort. Plus, old devices are hard to support in part because of decisions made in the creation of those old devices that make them hard to support. Like many other engineering things, if companies decided to get better at supporting old devices, it might be hard at first but it would get easier and easier as they got practiced and built solutions around it.
