> But then what is left to compare the two?

Countless other things about the way they work and how they handle what you want to do with them? We're not comparing radically different things, I was intentional about my comparison of Jeep vs Civic: they're the same basic tool, with different applications and contexts where they shine. This isn't an airplane and a bicycle.

Not really - a Jeep and a Civic is pretty similar in use case still. The Mac would be more like a tram that can only go on rails vs perhaps a bus. If we want to make some useless comparison.
