eBooks are great -- they're so much more convenient than paperback or hardback titles for travellers and commuters alike, especially if you're the kind of reader that devours long tomes on a regular basis. But e-readers generally have small screens and don't offer the same reading experience as a proper book. But Kobo's new Aura One e-reader has two vital statistics that avid readers will know well -- it has a screen the size of a classic hardback, housed in a chassis that's smaller than the thinnest airport thriller paperback.
