Definitely. It's also mostly Steve Jobs'/Apple's definition. But in the context of discussing Apple, many often solely talk about the shiny exteriors and looks of Apple products while neglecting usability. We may disagree, but the usability used to be and maybe is again the main selling (or at least "staying") point. I think this was lost a bit during Apple's "high design" years before Ives departure. It was often form over function.
