The iPhone Duo went on sale Friday and sold out within minutes. The estimated delivery time on Apple’s official China website has already been pushed back to seven or eight weeks. Starting at nearly $2,000—well above the Pro Max—it was still the only one of the Magnificent Seven to rise that day. An estimated seven million units are expected to ship this year, just 3% of total iPhone shipments. Volume may be modest, but the price speaks for itself.
