> Quality in the informal sense that is used in every day talk is how well a product/service fulfill the expectations of it's kind. When I think of "quality" in an informal sense, that's not what I think. I've got a cheap keyboard + mouse combo. They work perfectly well for what I use them for, but (I suspect) for less time, and enduring less abuse, than a higher-quality set of input devices would. I consider them low-quality, but suited-to-purpose. Something can be low-quality, but sufficient (i.e. fulfill my expectations, but be below the minimum specification level for what I'd call "quality"). edit: Although, I suppose that I'm talking more about my objective perception of quality than anything else.
