The iPhone has an about 50% of the us market share in the US and growing every year and 87% of teenagers have an iPhone. Why is this?

For me I think it’s a few things.

1: If you don’t have one you are looked down on.

2: A lot of people in the US use the standard texting app and not a 3rd party thus the Green and Blue bubble “fight” happens here. People don’t like making groups chats with green bubble users as it messes up the chat thus it forces them to not be in the chat or switch phones.

3: The iPhone is like the “first” smartphone to become big in the US so people are already used to it and don’t want to change.

4: it’s easy to use and people in the US want simplicity.

5: This I don’t know if it’s true or not but Steve Job is like an icon in the US so everyone wants his stuff.

I’m I missing anything that makes the US love the iPhone or do you think I’m wrong here?
