When Steve Jobs returned to Apple, one of the first things he did was crush down the product line, simplify shipping products to fit in a two-by-two matrix. On one side of the matrix, laptops and desktops. On the other side, consumer versus pro.

Things have really changed since that simplification. iPods, iPads, iPhone, laptops galore, desktops, pro machines, and now the Apple Watch, all with related accessories. But there is a critical difference. Tim Cook is a master of the product supply chain. He keeps the moving parts moving, the machine well oiled.

Neil Cybart, writing for Above Avalon, digs into Apple’s evolving product lineup, laying out some insights from Phil Schiller to give a sense of the direction in which that lineup is moving. Great read.
