Hmm, I beg to differ. If I remember correctly, the Apple Newton MessagePad was the first commercially available tablet computer. They may not have invented the tablet concept (just as so many other major inventions are conceptualized in fiction first), but as far as I know, credit for an invention is based on the first to actually make it. When I was a kid, I drew a space fighter. If someone makes a space fighter with a similar design, do I get credit for the invention?
