Amazon unveiled its digital-book reading device at the end of 2007, but in such small quantities that you couldn't really get one until 2008. While it definitely takes some getting used to the awkward placement of the page-forward and page-back buttons makes it easy for newbies to lose their place this is simply a terrific tool for people who love to read books. Travelers will especially enjoy the luxury of taking a veritable library on the road, and the Kindle can connect to a high-speed cellular network that delivers books ($9.99, even for new titles) on demand. Price: $359
