Another thing is, I'm pretty sure TNG's PADD inspired the modern tablet computer in general, and the iPad in particular.
Samsung tried to use the flat news pads from 2001: A SPACE ODYSSEY in their "prior art" arguments against Apple. So I'm afraid TNG has been scooped on the idea by a couple decades.
TNG showed touch panel consoles all over the ship, but was that feature ever shown on the PADDs?
