Isn't the point that it's integrated in the keyboard, so that you don't have to move your hands away to use it?

I'm on the lookout for a wireless ball mouse. I want to relive the glory days of cleaning out the little cylinders on the inside of the mouse without being constrained by wires.

This gives me an idea, does anyone sell these?:

    HEU   N
    DIN    U
     ^      M
    <⌄>   0.,E

With all full-sized keys? i.e. Numpad, arrows and home-end-insert-delete-pgup-pgdn? i.e. all the keys that Apple's laptops fucked plus numpad.

This is made for me.
