Mice? Mice, a desktop GUI, using both hands to type and using the mouse when needed? All stolen from Xerox bro. The smart phone existed before the iPhone with these things called IBM Simon came out in 1992, Palm, BlackBerry, and Windows all had smart phones out in the late 90s into the 2000s. Tablets all existed before the iPad sport. Dynabook concept in 1968 and Microsoft had a tablet PC available in 2001 with HP, Lenovo, and Acer all manufacturing models. And Microsoft coin the term tablet. I would give you that Apple is the one who innovated the mp3 player. but that is about it.
