>without Steve Jobs, someone else could have taken the spot
You could easily say that about the "true" inventors.
The point is Steve Jobs _was_ heavily involved in all of these major breakthroughs, spanning decades, industries, and personnel. He is an incredibly important and influential figure in the history of technology. Not sure why people feel the need to downplay his role when the very people he is supposedly stealing the spotlight from will attest to his genius (with the exception of Jef Raskin of course, who was a bit of a Svengali himself).
I think the difference is that the technologies Steve was so instrumental in creating were already being developed without him. The GUI and personal computer were pretty much already there, he just got to it earliest. Without him these things would have been created in just about the same time span with little difference.
This is distinct from, say, Einstein's theory of relativity, which was a solution from a direction which no one was looking. Everything Steve helped create was already underway.
I don't think that a concept computer costing tens of thousands of dollars that didn't exist outside of PARC's labs with an interface that didn't include dragging as one of its metaphors is "almost" the Macintosh, nor do I see much evidence for a industry trend toward a GUI outside of Apple's efforts and Microsoft's primitive attempts at copying Apple.
Windows 1.0 came out in 1985, only one year after the Apple Macintosh. PARC invented the idea of the WIMP GUI, not Apple. I think it's a little silly to say that the idea would have died within PARC.
Th idea of WIMP really wasn't "invented" at PARC. That organisation gets way too much credit. They amalgamated several concepts that had been developed since the late 1940's. I'm not suggesting that PARC's work wasn't important, but to blithely dismiss Apple's contribution and suggest that it all started with PARC it ridiculous.
Go and learn about Vannevar Bush and Memex, Ivan Sutherland and Sketchpad, Doug Engelbart and his contributions like the the Mouse and his oN-Line System. The history of modern computing is simply not as black and white as you are trying to portray.
Finally, anyone that has used both Windows 1.0 (and 2.0 for that matter) will tell you just how awful it was, especially when compared to the Macintosh. Microsoft didn't come close to the ideas presented in the Mac until 1990 with Windows 3.0, and arguably it was the 3.1 release in 1992 that was useable.
I wouldn't say smartphones were on the way to what iPhone was. In fact, if you re-watch the keynote where the iPhone is announced, the reaction from the audience is fairly muted, because people were clearly afraid that a phone with nothing but a touch screen for an interface was going to suck really badly.
