I think its a perfect analogy. With a car, its not about the road, its more fundamental than that. Its about the on demand speed, safety, reliability, efficiency and sometimes fun ability to autonomously move from point A to point B. In the same way that a phones fundamental function is wireless voice, data, etc. transmission from point A to point B, providing the user with total portability. All the networks, apps, etc. are just features that improve portability and autonomy, and continuously improve. On a car, the electronics, batteries, motors, chips, etc. directly contribute to the key tenants of efficiency, speed, safety, etc. and are all improving at the same rate as what's in your phone because the fundamental components are very close, in some cases the same. I don't see how any person would want an outdated version of something that decreases their ideal enablers of autonomy.
