The e-reader industry is obsessed with six inch displays, which are often too small to read PDF files or have much of a screen area to consume e-books. There are thousands of users all over the world that are demanding a 13.3 inch screen, but there is only one commercially available product right now, the Sony Digital Paper. What if there was an e-reader that gave you a better note taking experience than the Sony, but could also read any e-book format and lets you install your own apps? A new teaser video uploaded this morning shows off such a device. Details are scarce at the moment, but what do you guys think?
