CNET have published a review of the Amazon Kindle portable reader which lets customers wirelessly download electronic books, blogs, magazines and newspapers to a crisp, high-resolution electronic paper display that looks and reads like real paper,
'First off, while the Kindle may not be a whole new class of device (electronic-book readers have been around for a number of years), it joins the Sony Reader in making the e-book reader category a whole lot sexier and buzzworthy. While the Sony PRS-505 ($300) is the sleeker of the two devices, the Kindle is the more revolutionary in that it has a free built-in wireless connection that allows you to tap into Amazon's vast online bookstore from just about anywhere you can access Sprint's EVDO cellular data network.
In many ways, the Kindle is similar to the Sony Reader. At 10.3 ounces, the Kindle weighs about an ounce more and is slightly bigger, measuring 7.5 inches high by 5.3 inches wide by 0.7 inch deep. But both devices have 4.9-by-3.6-inch (6-inch diagonal), 600 x 800-pixel screens that use E Ink technology, which serves to make the letters and words on the screen look more printlike in their appearance--it's quite impressive if you haven't seen the technology in action before. Technically, it's an electrophoretic display, which Wikipedia describes as "an information display that forms visible images by rearranging charged pigment particles using an applied electric field." The Kindle's screen has 4 scales of gray and 167 pixels per inch, while the Sony's has 8 scales of gray and 170 pixels per inch, which means the Sony offers a little more in the way of contrast and is slightly easier to read.
