* Despite their supporters, e-books have yet to take off in a big way. One problem is that reading text on a screen is not as pleasurable as reading it on a page. However, Philips' latest creation, electronic ink, could change that. It uses a display that is covered with an array of tiny capsules which look black or white, depending on whether a voltage is passed through them. The result is a paper-like look on an electronic screen. Plus, low power consumption means you should get the equivalent of more than 200,000 page turns per charge. It's even possible to produce flexible displays that could be rolled up like a newspaper.
