Apple (AAPL -0.9%) roundup: 1) David Einhorn has scheduled a 2PM ET call to discuss his preferred stock proposal (webcast). Ahead of the call, he asserts the proposal is "a lot better" than a standard dividend or buyback hike. 2) As iWatch rumors grow, AppleInsider uncovers an Apple patent for a watch with a flexible touchscreen and a spring that allows it to conform to a user's wrist. 3) AU Optronics (AUO) has reportedly resolved its iPad Mini panel yield issues, and is working on the next-gen version. It might not be a coincidence the Mini is now listed as "in stock" on Apple's site.
