As if anyone except history books and nerds care who DID invent them.
What matters is who made them popular and got them in our collective hands en masse.
That's when the revolution starts, when people start buying them so you have improvements and cheaper price due to economies of scale, and you also get an ecosystem of apps, etc.
Tablets pre-iPad might as well have been non-existing. Same for smartphones pre iPhone. I had several (Nokia, Sony Erricson etc. After the iPhone you couldn't stand this crap for a moment).
I also had 2-3 mp3 players pre iPod. Including some bizarro Sony's own format players. Not even close to what we expect post-iPod.
