We wouldn't have, because Apple was the only company that was user-focused, not technology-focused.
Windows, RIM, Nokia, and others had all tried to produce similar devices. They invariably ended up with a clunking mess of buttons and features that appealed to geeks and/or business people, and no one else.
The genius wasn't in putting the parts together - although that was a significant achievement. It was in making a device that was uniquely beautiful, elegantly understated, and so easy to use it could (literally) be picked up by almost anyone.
No other company has ever taken the obsessive interest in design and aesthetics that Apple had under Jobs.
Not even the current Apple, which understands visual presentation, but seems to have prioritised ease-of-manufacture and profit margins over user delight.
Jobs was hardly infallible, but when he had a hit he hit it out of the park.
As for what we don't have - VR, smart home, and health, are all bumping along when they could be soaring.
The other big miss was handing content creation over to YouTube. Apple could easily have set up a content store to match/beat YouTube, as a follow-up to podcasts and the app store.
I have no idea if Jobs even considered any of the above. But Cook doesn't really get content, so Apple are unlikely to win big in these markets now - more likely to offer a not-quite-right product like Watch, which was mildly interesting, but not the game changer it might have been.
