Chapter 10 of Issacson's book spends quite a bit of time talking about Raskin vs Jobs on the Macintosh. Raskin is sourced several times for that chapter. The Macintosh would have been a very, very different product if Jobs had not taken over, and demanded a very different system than the one Raskin had envisioned.
The Issacson Analysis (backed up by Atkinson) was that Raskin had envisioned an underpowered, less expensive system that would not have had many of the features that made the original Macintosh "Insanely Great."
I like Gladwell's analysis - Jobs was a great _editor_ He didn't necessarily create very much, but he was driven to relentlessly critique until something great emerged.
It's amazing how valuable a function that can be, particularly in the presences of great engineers who can rise to the challenge.
The reason people praise Steve Jobs is not because he designed anything (though he may have had a few design suggestions) - but because his singular drive to release great products resulted in so many being created (and then, quite logically, being copied by everyone else)
The Macintosh, iPod, iPhone, iPad all came about because of Steve Jobs, and have changed the technology that we use every day. Love him, or Hate him, you can't take that away from him.
