APPLE'S IPHONE DUO SELLS OUT MINUTES AFTER PRE-ORDERS OPEN Apple's (AAPL ) new iPhone Duo saw its initial pre-order inventory sell out almost immediately, with estimated delivery dates slipping from October 23 to November 16–23. However, the rapid sellout may reflect limited initial production rather than exceptionally strong demand, amid reported manufacturing challenges. The key takeaway: Early demand appears strong, but Apple's constrained launch inventory makes the scale of consumer interest difficult to assess.(彭博社)
