Air Mouse Pro utilizes the touch screen in both displays, landscape and portrait. In portrait, the application allows you to type using the built in full featured keyboard, while still offering ample space for the mouse pad and left and right click buttons. It also includes a scroll bar between the left and right click keys. On the other hand, landscape is used without a keyboard to make moving around and clicking easier on the longer screen. I feel that the screen sizes are reasonable for both modes and the keyboard does not get in the way when using portrait mode. Also, none of the buttons are hard to reach since most users are already accustomed to the small iPhone keyboard.
The Air Mouse software that the developers provided also is simple and to the point. The clean design has only four tabs with easy to understand directions that allow you to change how fast your mouse moves and other basic features such as hotkeys.
