So you  as the the possibility of having a a graphical display on it , like a screen ? Like the iPod ?
You can have an L_C_D_ screen. Um but therefore no rubber will be used.
Right.
Alright ? So plastic yes , titanium yes , but this will of course influence the form. With plastic , as I understand it , you can use any form. Um latex is tricky. Or rubber and um and titanium also seems to be tricky when it comes to the form. So the way to go is if you want a scroll wheel you either make it flat and angular , uh add an L_C_D_ screen , and um then you can basically choose either plastic or titanium. Or wood even.
