The Future of Reading, by Steven Levy, Newsweek, November 17, 2007: "...the Kindle...has the dimensions of a paperback, with a tapering of its width that emulates the bulge toward a book's binding. It weighs but 10.3 ounces, and unlike a laptop computer it does not run hot or make intrusive beeps....with the use of E Ink, a breakthrough technology of several years ago that mimes the clarity of a printed book, the Kindle's six-inch screen posts readable pages... (The Kindle gets as many as 30 hours of reading on a charge, and recharges in two hours.)...E-book devices like the Kindle allow you to change the font size: aging baby boomers will appreciate that every book can instantly be a large-type edition. The handheld device can also hold several shelves' worth of books: 200 of them onboard, hundreds more on a memory card and a limitless amount in virtual library stacks maintained by Amazon. Also, the Kindle [costs $399] allows you to search within the book for a phrase or name...Some of those features have been available on previous e-book devices, notably the Sony Reader. The Kindle's real breakthrough springs from a feature that its predecessors never offered: wireless connectivity, via a system called Whispernet. (It's based on the EVDO broadband service offered by cell-phone carriers, allowing it to work anywhere, not just Wi-Fi hotspots.)"
