To stick with your car analogy though, with screens it's more like the performance vs. gas mileage trade off. Your sports car will get you the same place at the same time (capped by speed limit) with more fun (if you like that sort of thing) but cost you at the fuel pump. This is fine if you don't care about $/gallon, but sucks if there is gas rationing. This analogy is also flawed, of course.
