Bloomberg Businessweek has a fascinating, in-depth look at how Apple’s supply chain enables it to continue to churn out top-notch hardware at competitive prices. Meanwhile, All Things D covers a new document from Cannacord Genuity estimating that Apple claims 52 percent of the handset industry’s overall operating profits, despite owning a mere 4.2 percent of the worldwide handset unit market. It’s no wonder, then, why Apple opted to replace Steve Jobs with Tim Cook, the company’s longtime supply-chain guru. But as my colleague Erica Ogg notes, a big question going forward is whether Cook’s Apple becomes less conservative with its massive checkbook than it was under jobs.
