Amazon has dropped the price again on their original 6″ U.S. Kindle ebook reader to $259. They have also introduced a discount on their International Wireless Kindle edition making it $279. Previously, there was a Kindle price reduction of $299. Now you can carry around your reference book and more for the same weight and dimensions as a copy of just the PHP reference book! Sleek and lightweight, Kindle is as thin as a typical magazine and holds over 1,500 books. An advanced display reads like real paper and boasts 16 shades of gray for clear text and crisp images. The current generation has improved page refresh: faster page flips as the e-ink changes the entire page. Even better, small changes to the page don’t require a full refresh (the black-white flash) of the entire page!

A kindle version of PHP Reference: Beginner to Intermediate PHP5 is available for $8.99 through Amazon.com, at just over half the price of the main book!
