I'm disappointed this is for Android 2.2 and up. Not all of us Android users have that available nor are we finished our contracts that allow us to upgrade to a new device.
Facebook should have made it compatible with at least 2.0/2.1.
Facebook on Android is a consistently bad experience. What's worse, I occasionally deactivate my account for periods of time to focus on school / work /etc. The app comes pre-installed on my HTC so I can't remove it. However, it keeps trying to authenticate and randomly gives me can't-authenticate errors or launches the browser to a facebook login. Pretty disappointing experience.
The design and how it works when it works is pretty good in my opinion, but stuff like what you mention is making me hate the facebook app with a passion. If I get for example a "1 new message" notification, and I press it, nine out of ten times nothing will happen or the app will open to a blank messaging screen, showing nothing (and will stay that way).
