Agree with your question...

"Older" is a relative measurement of time, but doesn't say anything about the marginal benefit or cost.

An example of your question I see from Japan relates to payment systems. People often critique Japan for its cash-oriented systems and have also observed the difficulty that digital payment systems have had in gaining traction in Japan... an example for why digital payment systems have had poor adoption is the existence of earlier, well-adopted solutions that provide many of the same benefits in the majority of practical scenarios (i.e. stored value IC cards: Suica/Pasmo/etc.). In cases like this, the "newer" and supposedly better technology doesn't provide as large of a marginal benefit. They already solved much of the problem.
