An analogy is not a valid argument. Analogies are useful for illustrating a concept, but a waste of time when trying to support a claim. Also, your analogy does not seem analogous to me.

Analogy isn't any kind of argument. It is an aid to understanding.

I agree. We're talking about phones, not a restaurant.
