I'm sorry, I don't understand why it isn't a good analogy. The comment is saying that nanometers really only denote the technology generation, and that is exactly what 3G and 4G denote. There is wide variation between 4G phones, as there is wide variation in 10nm processes. The analogy seems ideal.
