Have you ever had a really, really good hamburger bun that set the burger apart from almost any other burger you've ever eaten?

If you have, why not describe it as "artisanal"? Some bread really is good enough to warrant a special description.

Likewise, the iPhone 5c is a really, really nice plastic object. I know next to nothing about plastics, but I do know that the 5c is set apart from, say, this Handspring Visor that's (for some reason) on my desk.
