But today's Apple isn't all he was...
CEO of Pixar, commercialised the mouse and graphical user interface as well as pioneering typefaces for computers, PC and Mac alike. None of this would exist if it wasn't for Good ol' Stevey.
Not to mention what state the phone and tablet would be in if it wasn't for the iPhone and iPad, there's no objecting that every other company copied those devices, and while I prefer the Android platform over the iPhone I know it wouldn't exist if it wasn't for Steve's original idea for the iPhone.
