Amazon is set to release the new Kindle 3 on August 27, and it is now available for pre-order. Early reviews are making it sound pretty impressive. There are now two models: one with wi-fi only($139) and one with both wi-fi and free 3G($189). Both are slightly more compact and lighter weight than the second generation device but have double the storage capacity, better contrast screens, longer-lasting batteries, and have been described as a bit faster (see Yahoo! News). Many of the changes seem fairly minor, but reviewers familiar with the previous generation have been quite positive about their implementation. I'm glad I waited.
