This means that the right and the bottom border of the touchscreen can be mapped to a scroll function and the other area just to control the mouse. This would make the mobile phone to a very handy keyboard & touchscreen unit.
*) You may ask why I don't use the PC's keyboard and mouse instead... Sometimes I sit with my little baby boy at the PC and it's difficult to use a fullsize keyboard with him sleeping in my arms. But If I had a very small device in my hands then I could easily control a web browser and read some news, etc...
