You’re in the middle of a Tom Clancy novel, immersed in a world of espionage. Then you get a sudden urge to reread Moby Dick . Because you’re reading on an electronic device, with the push of a button you can make the spy novel’s text disappear from the screen and replace it with Melville’s masterpiece. That’s the beauty of e-book readers. Like the iPod, which lets audiophiles carry their entire music collections in a gadget smaller than a deck of cards, these devices let avid readers haul dozens of books in a single lightweight tablet the size of a small paperback.

But that’s still too big for some consumers, who’ve grown accustomed to electronic devices that can slip into a pocket. So goes the thinking behind the Readius e-reader from Polymer Vision in Eindhoven, Netherlands. The company, which has a number of patents related to superthin flexible electronics, has created a rollable display using that technology and low-power, image-stable reflective-display technology from E-Ink Corp. of Cambridge, Mass. The display can be read under various lighting conditions, including direct sunlight, from all viewing angles.

What's the largest criminal enterprise in the world? Narcotics? Gambling? Human trafficking?

Nope. The biggest racket is the production and trade of counterfeit goods, which is expected to exceed US $1 trillion next year. You've probably suffered from it more than once yourself, purchasing on Amazon or eBay what you thought was a brand-name item only to discover that it was an inferior-quality counterfeit.
