well obviously the all in one social networking is nice but personally my favorite is the contact feature where it says a contacts most recent tweet and status so you know if you want to answer it as well as showing their most recent profile pic. Frankly though i enjoy most of the features, at least in concept, and would like to try it out whether its a rom or copy of motorola's code in which case you could improve the app more than likely such as making options for who and what goes in what widget etc. here is a website that shows most of the features
