- This reduces the number of types associated with input; adding a distinct input type doesn't introduce a whole new enumerated type and related functions. - Special handling for different devices is needed less often. If you want to respond to an F1 press, simply check for KEY_F1; the device type doesn't really matter (though it'll usually be a keyboard). - This allows cleaner support for generalized USB devices. While they're usually of the traditional classes (keyboard, joystick) with associated inputs, they don't have to be. - Forced casts between parallel types can be removed, and weakly-specified variables (ints instead of the enum type) can be fixed. Some things that might have been merged havn't; for example, arrow keys on a keyboard (KEY_UP) are still distinct from axes on a joystick (JOY_UP). These may or may not be merged in the future. Some were: removed PUMP_ symbols. Treat them as generic buttons, and just give them names with GetDeviceSpecificInputString. It's not worth introducing more special names for something only used in one place.
