The issue here is that for most people (as opposed to highly paid tech workers) these items are all luxury items that are rarely replaced, as opposed to food and energy which are necessities of life. I know a number of university students who are using 4-6 year old laptops to do their work. The fact that they can get a better laptop for the same money is irrelevant because they are spending that money on things like gas to get to classes and work.

I think the point stands. A 4-6 year old laptop today is significantly more powerful than a 4-6 year old laptop 15 years ago.
