Being a "star" has almost nothing to do with being a good person. It's persona. Jobs has a very compelling life story. He approaches his work with the relentless perfectionism and devotion of an artist. He understands the value of theatrics and suspense. He's reclusive and arrogant but also charming. He's simply a more interesting character than Bill Gates who was a rich kid that went to Harvard and got even richer. I admire what he's doing with his money now but it doesn't change the fact that he's a boring character.
