Apple isn't in the "develop and update" business. They are in the "differentiate and capture" business and their monitors are still different enough and their customers captive enough that they really don't have to do anything to continue selling what they have.Why does it take Apple YEARS to develop & update displays, where the competition can do it so much more often, including new features as they become required. It's not like Apple manufactures anything itself, its just outsourced panel production and the whole thing itself is too.
