> Mindblowing - no doubt. Changing social culture though? What change did the walkman bring about?

- Music went from being a social activity to something you could privately enjoy

- You could listen to music wherever you wanted, whenever you wanted

- It was the first time, bar maybe some niche LCD games, that electronic entertainment was portable

- It was also the start of the decline of social interaction. Where people would put their headphones on and shut out the rest of the world. eg no longer chat to strangers on the bus.

Sure, there have been bigger changes to society, like the web, like micro computers, like kitchen appliances or even the car. But the Walkman is probably the least discussed and least credited of them.

> The iPhone expanded the reach of the internet on everyone's lifes and revolutionized social culture and brought an enormous individualism:

That was already happening with or without the iPhone. Don't get me wrong, it certainly help accelerate things, but it wasn't the only device out there nor even the first to do this.

> expanded instant messaging, dating apps etc. enabled a lot of interaction but among highly selected individuals or groups

Maybe in America, but that wasn't true in a lot of other continents. In the UK (for example) people still primarily used text up until relatively recently. Here the iPhone was largely just another handset (London is a slightly different story) and by the time smart phone apps became a thing the average person cared about, Android was already outselling iOS. The iPhone didn't really create that market either since feature phones would have services like this too. Again, I'm not saying the iPhone wasn't a contributor. But it your point was that is was at least mainly responsible for, and that simply wasn't the case in Europe.

> the narcistic selfie with an attractive filter replaced the group picture and changed how people view themselves

lol you do realise that people were doing that with disposable camera's in the 90s? I know this because I'm an old fart who used to do just that when out with mates. I have albums full of pictures printed on card (remember when that's what people would call a "photo") of such images with myself and friends in clubs, bars and holidays.

The iPhone wasn't even the first camera phone, nor even the first phone with a "good" multi-megapixel camera. That was an established market and an expectation that high end phones should have.

> navigation apps

I ran Google maps on my Sony Ericsson several years before the first iPhone was released. Some of my mates ran mapping software on their PDA's before me too. Fair enough these are edge cases but you're still forgetting about Android.

> review apps

Yes, that massive pivot in society, "review apps". But again, not an iPhone exclusive.

> spotify etc. enabled an individualistic movement through the world, individually entertained and shielded from strangers and random encounters

Aside from the Spotify branding there, you're literally just describing the Walkman!

Don't get me wrong, the iPhone definitely had a big cultural impact. But you're massively over attributing changes the technological and social landscape to one of what was actually many similar devices all making the same inroads in the same decade. Yet it was the Walkman (and similar cassette players) that started that journey in the first place.
