BlackBerry Messenger
RIM has put a fair amount of effort into revamping its BlackBerry Messenger app, which was once the sole reason anyone under the age of 25 owned a BlackBerry. Now RIM has given BBM the ability to place voice and video calls over Wi-Fi. It even enabled a screen-sharing feature that allows you to broadcast your screen to whomever you're talking to.
But BBM exists in its own universe, unable to connect to other services. Unless you're surrounded by BlackBerry users, you won't have much use for the app.
