While I am a satisfied user of the stock Messaging app (mixed with SMS Popup) that comes with the Galaxy S II on Android 2.3/4.0, there are plenty of people out there who prefer a messaging app that does more than just send/receive text messages. They want abilities like being able to schedule texts, receive pop-up notifications, voice input/output, a nice home-screen widget, blacklisting, favorite contacts etc. etc.
