I remember it. Using a third party device (especially like, an actual iPad) hardly counts as hardware theft.
The examples you gave solidify my point. Those innovations from Nintendo were good ideas that were only copied after it was clear they were.
Your point was that they only copy it if they already were a success.
Wii hadn't even launched then Sony decided to scrap their boomerang controller and shove some gyros in a Dualshock 3.
It was so transparent how much of a last minute reactionary move that was to the Wii's buzz, I'm surprised that someone would even try to deny it.
