Amazon only just released a new Kindle Paperwhite e-reader two months ago, but were already hearing rumors that a newer model is on the way. According to a new report from TechCrunch, the new version, to be released in early Q2 of next year, will boast a sharper 300-pixel-per-inch screen, allowing it to better compete with models like the Kobo Aura, which has a 265-ppi screen. (Not that Kobos represents much of a threat to Amazons book-selling empire.)
