So Schiller&#x27;s explanation was really just making explicit the problem described: he more or less states that the goal of each product is to bring into question the necessity of the next. If every product you make, is by design, meant to obsolete another product, then it&#x27;s going to be a lot of hard choices for the customer: every single thing you want to buy comes with the &quot;but maybe this thing can do this too...&quot; question. This doesnt really justify or bring insight into anything, but rather accurately predicts the confusion such a product line will create.<p>Once upon a time apple wanted you to walk into an Apple Store and walk out with something useful, now they want you to consider where you side in the &quot;personal vs power&quot; debate.
