Amazon now has a free Kindle app for the iPhone and iPod Touch. I installed it this morning on my Touch, typed in my Amazon account information (email and password), and zoom: almost instantaneously, the app grabbed the listing of the 12 books I have on my Kindle.
I tapped a few of them to add them to the Touch for viewing there, and each one opened where I had left off when reading them on the Kindle. The viewing is nice, although it does not support zooming of pictures embedded in the ebooks. (Zooming of pictures is a feature that was added to the Kindle via easy-to-install software upgrade 1.2, or via purchase of the Kindle 2.)
I’m pretty impressed with it. The only downside I see so far is the lack of picture zooming. I have also heard that it does not support tables. Otherwise, a very nice little app that is off to a great start.
