Chatting
Perhaps one of the most practical uses for a PS3 keyboard is to chat with other players during online gaming. Without the keyboard, the player is required to enter letters one at a time using the game controller. The keyboard allows for fast communication, which means less delay during the game.
Internet Browsing
The PS3 allows for Internet browsing, which can take a lot longer using just the controller. The keyboard allows the user to quickly perform Internet searches while the built-in mouse makes it easier to navigate through links.
Mouse Functions
The PS3 keyboard comes with a built-in mouse. This makes it easier to navigate during online gaming. A player can navigate using the normal control, but it is much easier and smoother when using the mouse. Because the mouse is built in to the keyboard, there is no need to have an additional surface to play on.
