Amazon's Kindle and other Android eReader Apps
says: Amazon's Kindle app is finally available on the Android. Although it's the most high profile eReader app released to date, it's not your only option. Check out all these eReader apps to decide which is your favorite.
Now you can sync the ebooks you purchased with all you devices, including iPad, iPhone, Android, as well as your desktop and Kindle. Purchase any book available for the Kindle (over 600,000 titles!) right from the app. Reading is also made super easy. The device will save your font and brightness settings, not to mention it will keep track of the page you are on.
Laputa Reader(Free Books)
This has been my defacto book reader for the Android. It's free and has a ton of free titles to choose from, although not nearly the selection the Kindle has (but Kindle books are $10 a pop). It also has some neat features. A library for all your titles, bookmarking and a page flipping feature.
All in One - Comics
So if you read my "Lovers of Classic Comics" list, you're familiar with this app. This Beekeepers app is the ultimate reader for all those old comic strips you know and love. It also has some awesome searching and sharing features as well.
