I think that the trackball is a good idea, but as for an adequate substitute
for the mouse I think it leaves something to be desired.  First of all it
takes more effort to be accurate with the track ball than a mouse.  Also mouse
users do not have the wrist problems that can result from trackball use.

I also think that to put any mouse or trackball type device on the keyboard
will make matters worse.  A person will not be able to type and use the mouse
at the sametime, nor would they a trackball, regardless of the location.
So I don't think it matters where the location is.

So what do you suggest?
I am glad you asked that, what about a thumb joystick type device, one that
would allow the user to move the cursor around in a more or less 90 degree
fashion, which would make things more accurate.  Maybe that would work.
Such a device would probable work being located at the bottom of the keyboard.
