The machine has a touchpad, but I had to turn it off, because
otherwise the mentioned device wouldn't work (it emulates a
serial mouse). But even then, This little girl -also known as my daughter-
has hands and arms which she barely controls, so she smashes
them on the laptop every now and then. No problem for the keys
(no events are bound to keys), and the display is just far
enough away so she can't reach it, but the mousepad is too
close...one touch would be too much...
