I can't even begin to enumerate the things you see everyday that are influenced by Apple, besides their own products.
Or he just used smart and predatory business practices, and somehow was the only major player to realize eyecandy will win over configuration for everyone that wants just a "tv" into the internet.
No, he didn't do all this himself, but he was captaining the ship. Has Sergey Brin changed the way people use the internet?
Let me Google that for you.
Google however turned a better product and has therefore captured the lion's share of the market. But they Google search engine is pretty much a copy in functionality of previous ones that came before.
Of course Google have brought other things to the internet (maps comes to mind), but the search engine didn't change how people used the internet - we were searching long before Google.
- Sub-second reconnection to wifi when resuming from sleep, using past remembered networks and IPs
- Bonjour zero-configuration service discovery for printers, network speakers, etc.
- Exposé window management and the GPU-accelerated desktop in general, not to mention just-in-time-compiled GPU accelerated image and video manipulation with CoreImage / CoreVideo.
- Spotlight indexed desktop search that's actually usable for real world filetypes
- Quicklook instant previews, not to mention native PDF support not involving Adobe Reader
- A mail program that autoconfigures based on just the email address, just by trying the obvious options
Add in the fact that Apple is still the only company to have multi-touch work properly on a desktop, that their hardware has been dominating geek conferences for years because of its travel-friendlyness, and there is plenty of innovation to go around.
In what way has multi-touch been pushed way past what anyone has done in the past? (say, compared to Sears et al work from 1990?) Actually, any of the technologies on that list, in what way were they pushed way past what anyone else was doing in the past? Cornering the music industry (legally) was an achievement indeed, but a tremendous contribution? My thought goes back to Wallmart and any product that they was first to successfully sell.
