Kindle for Android

I downloaded Kindle for Android a week ago, and have been dabbling with it. My first impression is about what I expected--a nice option, but the phone is really not a very pleasant platform for reading a book! High points:

1. Works very well, and is pretty quick.
2. Well-integrated with the Amazon website--allows my preferred smartphone paradigm of doing as little data-entry as possible on the phone.
3. Has a very broad selection of font sizes.

The single biggest disappointment? Does not enable one-handed reading by providing a good Page Down option. The Dolphin browser remains the only Android app I have found that implements this very obvious feature, which provides parity with the Palm Pilot c. 2000!
