That's just semantics.
"Made them right / what customers wanted" covers so much ground for those products, it's fair to say they were first in a new category of product.
For example, "smart phone" means "phone that works like an iPhone", more or less.
I would vote for mobile internet.
Yes, Blackberry had a smart(ish) phone. But it was really just a mobile email phone. Apple was the first phone manufacturer to provide a full featured, no compromises mobile internet browsing experience.
I would then add the whole mobile app store concept. Blackberry's version was really nothing much.
Nah, he borrowed/stole this too from others(his words, JFGI:artists+borrow+steal+jobs).
What product categories did Steve/Apple invent? All of their major breakthroughs (iPod, iPhone, iPad) were already existing product categories but Apple just made them right / what customers wanted. Correct me if I'm wrong.
