The digital revolution? The frugalista movement? Social networking? Or As-seen-on-TV products? 2008 has changed the landscape of how we recreate, communicate, shop, and dream. What product would you consider the Best Breakout Product of 2008?

Amazon Kindle

Amazon's (NASDAQ: AMZN) Kindle is not the first attempt to replace the paper book with an electronic reader, but it has succeeded (and how -- even now, over a year since its launch, the wait time for a new unit is a couple of months) where others failed for several reasons. The first is the reading experience. The Kindle's cutting-edge electronic paper technology provides crisp, clean print in any light conditions. The device is thin and light enough to carry anywhere, and can store hundreds of books at your fingertips.

The second reason for its success is the access to a huge library of literature, which can be accessed via a built-in wireless link (no computer needed) through the Sprint cell phone system. Virtually all new books are available in Kindle format, and many, many others (190,000 and counting). Top newspapers such as the New York Times also offer Kindle subscriptions, and schools are beginning to adopt it as the platform for electronic versions of textbooks. In the race to lead the transition to electronic books, Amazon's Kindle has broken free of the pack.
