Having short cuts to all your games in one place.
Access to the Steam Overlay. Let's you press shift-tab in a game to overlay your friends list, any messages from said friends, and a webkit browser over the game being played.
It announces to your friends what you are playing or what you want them to think you are playing. When adding a shortcut to a non-steam game you get to name it whatever you want. So when I run WoW through Steam my friends see "Dudeman is playing non-Steam game 'Nick has full blown AIDS' " or any jacked up message I want everyone on my friends list to see.
