Again that depends on usage scenario. For example can you sign your name with 
a trackball? Or use one with gloved hands?

This is a case where there is AFAIK no one size fits all sensing technology; 
if there was then we wouldn't be having this discussion. Going to a capacitive 
screen will allow GTA03 to be used in some scenarios where GTA02 can't, and 
vice versa.
