New flexible batteries and OLED (Organic Light Emitting Diode) may lead to foldable computing. From Dani Fankhauser at Mashable: “Innovation in lighting is great, but the real game-changer is when OLED is used on a flexible surface for a bendable device. ‘The first benefit will be thinner and lightweight, less breakable displays,’ say Janice Mahon, VP of Technology Commercialization at Universal Display Corporation.

She describes what industry insiders call a ‘universal communication device,’ which is essentially a pen, but with a display that rolls in and out. It seems our aspirations are towards forever smaller devices.”
