Original post
I’ve really enjoyed using the kindle 2 and kindle 2 DX. It’s great being able to take a bunch of books on a trip and have my reading bookmarks synchronized between devices. So I’ve been really curious about the latest generation of kindles.
These kindles have many improvements over earlier models, greatly enhancing the reading experience. To me, one of the the best improvements is the higher contrast screen, which makes the text much sharper. The page-turns are faster as well.
Here’s an example of the kindle with its higher contrast screen:
The unit itself is a new color–slate gray, which many will find to be an improvement. In addition, this kindle is lighter than previous generations and has a longer battery life. Previous kindle features are also included in this generation–lots of storage for books (holds about 3500 books), new book downloads in about 60 seconds, whispersync (to synchronize reading bookmarks between devices), text-to-speech, and portrait and landscape views.

If you are looking for a case for your 6-inch model, I would recommend the M-Edge Latitude Kindle Jacket
Here’s a pic of the kindle inside the M-Edge case:
So, with all the new updates and features, as well as the big price reductions, those resisting the urge to try an ebook reader no longer really have any excuses.
