To me, the extra utility of the Corolla is like the extra utility of email, text messages, phone calls, web browsing, exploring the limits of analogies on HN, and so forth.
I can do those on a phone, but not on a camera. (Actually, I'm sure that somebody has a camera that lets you send and receive mail, that's Lett's and Zawinski's Lwas...)
But if you were to talk about a cube van... We'd have something. A cube van won't fit in my garage, just as a camera won't fit in my pocket (Yes, I used to own a Casio that did, but still...)
A cube van is extraordinarily inconvenient for anything except moving my entire house. For all smaller jobs, my station wagon rules. But when I wanted to move house, I hired a proper cube van.
And if I ever need to take an amazing picture, I would probably use a proper camera.

But all that being said, Steve Jobs did compare pickup trucks to desktop computers at an earlier time. If he were here today, he might suggest a laptop is a pickup and an iPad is a sedan.
So you might have something.
