Apple’s iPhone Duo hands-on: What works and what doesn’t on its first foldable

Apple's foldable iPhone Duo hits stores Friday, but preorders sold out almost immediately, with deliveries pushing into January. Yahoo Finance tech editor Dan Howley goes hands-on with the phone, from its 7.6-inch inner display and 5.4-inch outer screen to its cameras and Duo Preview, which lets the person in the photo see the shot before it's taken. He also explains the biggest first-generation drawback: not every app has been optimized for the larger screen yet, and why iOS developers may catch up faster than they did on foldable Android phones.
