For Android users without apps2sd (via hacks or froyo) it's not worth it yet, but shows promise. Unfortunately, it weighs in at a whopping 17MB installed, and doesn't even integrate the B&N store into the app, sending eBook purchasers to the website instead. It has a refined interface, not quite up there with Aldiko, but definitely a good experience. Notes: If you own a nook, this is the mothership. Even better, for those who have rooted their nook color devices, it's like having Kindle and nook in one unit. When you pick up your Kindle at home, you guessed it. If you read a bit on your Kindle at home, you can pick up where you left off on your smartphone on the commute to work. The best feature for those already using Amazon's Kindle is that the Android app 'knows' where you stop reading. Notes: Most popular eBook application in the market at this time. Books are stored in the cloud, but may be downloaded as ePub or PDF files. Notes: Google has introduced book purchases into their update of the old Android Market, making it easy to buy apps, books, and music. It's definitely worth noting that =X= has most of this information in the mobileread wiki at this location. I'll make sure to give credit and karma when possible. I don't read primarily on an Android device anymore, so if anyone finds something that has changed, is inaccurate, or a great addition to the list, feel free to comment here or send me a PM.

I first created this list in early 2010 when I was using my Android phone to keep up on books while waiting for my nook to arrive from Barnes & Noble.
