Good for Apple for paying for iconic design.
Irresponsible? Paying a legitimate license fee for a design that is justly displayed in museums hardly seems irresponsible. One of the things that separates Apple from companies that make ugly products is that Apple cares about beauty and design, as well as beautiful design.
Samsung and other race-to-the-bottom-with-cheap-crap companies would certainly have never have considered doing this. And that's what makes Apple special.
