Tim Cook talked about his five years at the helm of Apple in a wide-ranging interview published Saturday. Apple fans looking for juicy morsels about new products won’t find them in the Q & A, however. Among other things, Cook discounted the bleak claims of those analysts who maintain the smartphone market is in decline — and Apple’s fortunes with it. The smartphone product category’s best days are still ahead, he suggested. Cook’s view isn’t just wishful thinking, according to Tim Bajarin, president of Creative Strategies.
