Prime View International -- the company responsible for pumping e-ink screens into Amazon's Kindles -- has recently shown off some color and video screens at a trade show in Shenzhen, China. The company has been showing off the displays in 6 and 9.7-inch varieties, one of which could fit perfectly into the 6-inch Kindle, of course. While there's been no real indication that Amazon is interested in transitioning to color or video-boasting readers, but it's not completely inconceivable considering the recent competition it's facing.
