The Apple II was a genius product for reasons that had NOTHING to do with: the case, the logo and the advertising.
Well, yes... but there are many things that are genius that I have never heard of. And plenty that I know of that will never be well known.
no one cared what color the case was
Well, Jobs did. As a programmer with some depth, I know how little engineers care about product development and marketing. Great things sell themselves, right? I used to agree, but after seeing the waste of unwanted products and the tragedy of unused pearls, I can no longer believe the Field of Dreams mantra (If you build it, they will come). The guts of the Apple II didn't sell themselves, and the color of the case does matter to buyers. Certainly it was a feat of engineering that would have been impossible without Woz. I also think that it would have been a forgotten player without Jobs.
