How to get a better Facebook android app
The Facebook android app is very slow, (this link explains why). A solution suggested by the author is to use the m.facebook.com webpage. You can make a link to this webpage an app style icon on your desktop with the Chrome beta app.
Login to the facebook app on the browser and click (sorry touch) the 'add to home screen' menu item (more details here). Then a shortcut will be added to your desktop which will function like the Facebook android app, only a million times better.
