I think there's a difference between "depend on" and "use." Most everyone that currently has an iPhone or Android is going to use those features.

But for every Youtube video that I watch on my phone, I watch many more on my computer. I use my phone for browsing HN and Twitter, taking pictures, checking my email, and of course getting texts. I have a banking app installed, but that's not the reason that I have a phone.

I would have to post to Instagram from my computer, but other than that, I could use a PinePhone. Unfortunately, it looks like the only positive of the PinePhone right now is "free software." But my point is that it's possible for PinePhone to convince me by adding brand new features—they don't necessarily have to support every iPhone app to win users over.

A bit irrelevant, but I don't think you can post to Instagram from your computer, got to use the app.

It used to be that you could use developer tools to emulate a smartphone and be redirected to the mobile site, which would let you post.

It seems that you can still post from the web version of Instagram on mobile (just tested it now on Android Chrome) — I should imagine that it still works in the DevTools mobile emulator (though you do have to refresh the page).

Using the Instagram PWA may be a viable way of using Instagram on mobile Linux. Still can't seem to post stories on the PWA, though.
