Maybe, but Apple could easily negotiate a contract with some other print-on-demand company if they wanted to.Is the demise of the Apple photobook connected to the demise of Kodak?
My guess is that there is no longer a competitive point. There are many good print-on-demand services that make photo books for a reasonable price. Apple is not interested in a service where they have to compete on the basis of price alone - that leads to cutthroat pricing and a "race to the bottom" where you must sacrifice quality to compete. So they bow out and let everybody else compete for those customers who still want printed books.
