Jobs sold a much better product in most cases; Gates used unfair and monopolistic business tactics to extract wealth and power above and beyond the actual value of his contribution.
All apple products are closed. You can't change out the hardware, software, and in the case of things like the ipod, the batteries.
Jobs was a great visionary, but you can't tell me that he didn't use the exact same sort of tactics. If he had one the PC war, we not only would have closed software, but closed hardware.
It's not physically impossible to change the hardware, software, or batteries of any Apple product, it's just not designed to accomodate that. By selling a separate OS to multiple different PC vendors, Microsoft actually employed the exact opposite tactic, and that hasn't exactly been an unvarnished success.
It's counterfactual to speculate on what Apple might have done if they won the PC war. The fact remains that Microsoft abused their monopoly to undermine Netscape and Java and stole the source code to Quicktime.
