I've used an Apple II, there's one in the Smithsonian, but never heard of Xerox making a computer. Guess which one had more impact.
As for smartphones and tablet PCs, reading is a skill. I never said he invented them. I said he made them popular.
As for the pharma analogy. When is the last time they cured something? No their big claim to fame is a dick drug that was intended to do something else.
There won't be another like him in this life time. These are once a generation people. I would associate his success on the level of Edison. They changed the world.
In the late 60's and early 70's Xerox's PARC had a lab that created the GUI, laser printers, and networking as you know it now. Xerox did nothing with it but either allow the enginnerds to buy the patents or sell what was developed. Adobe, 3Com, and Novell all were born from that lab. Great book to read is
Accidental Empires, or watch the supporting
Triumph of the Nerds documentary.
Xerox sold the GUI concept to Jobs to ensure that Microsoft and IBM specifically would not have it. Apple made sure that the Adobe got on the map with the laser printer wysiwyg printing language with the original Mac (Apple sold the laser printers, and HP initially licensed it until the patent expired, then HP owned it all).
But you hit the point, that while Apple did not necessarily invent something new, they did push existing technology to the forefront and degeekified it. That whole Microsoft drum beat of OS integration and oi glaven products in the early 90's was an attack on Apple being too simple and not geek enough.
But the point being is that Apple used existing tech and pushed it forward. Not always as the front runner, but pushed forward none the less. Many companies have followed suit with even some of Apple's failures or realization of the possible with the market:
- Cube = ultra small form factor computers are possible.
- Mac Air = everyone made vastly lighter laptops not called netbooks.
- iMac = All-in-One computers...and Apple had 'em with touch screens with the 2nd gen iMac).
- iMac with colors = everyone made non-beige computers
- Copeland OS = Windows 2000 for some and Windows XP for the rest of it.
- Plug-and-Play in the early 90's = Microsoft had to do it too.
- Object Oriented Programing and reusable\shared\standard objects as OS norm= more stable OS\apps\and Microsoft had to do it as well....just took them a long time.
- Newton = yup others tried in the 90's as well (iPac), all failed...now they are trying it again, I wonder why?
