We have absolutely no evidence that Apple is working on a foldable iPad, but it's always nice to dream. Taiwan-based designer Hao-Chun Huang's Flexbook concept tablet folds into a variety of configurations, comes with an attached (also foldable) keyboard, and has a 21:9 ratio display that swivels 180 degrees. Its rubber skin doubles as a protective case when the device is folded up. OK, maybe we'll see one in 10 years--or longer. Come to think of it, with its bright colors and flat keyboard, the Flexbook has a lot more in common with the Microsoft Surface than the iPad.
