Except Apple isn't really for the rest of us. Outside of America and a handful wealthy western countries it's for the top 5-20% earners only.

Approximately 33% of all smartphones in the world are iPhones.

60% in the US

Maybe the suspicion is the top 5% carry six smartphones?

Who do you think this presentation is geared toward?

In the EU the market share is 30%

Yes but not evenly distributed, BeNeLux, Germany, Austria, and Nordic countries have a lot of iPhone users, while moving further east (or south) you see lower market share. Maybe it’s “two handfuls” of wealthy western countries rather than just one, but I think OPs point holds true.

One average American user is probably worth 5-10 average European users.

(I've dabbled in mobile games)

Yes. Americans are THE most valuable customer base, y'all use insane amounts of money on mobile crap.

And non-mobile crap. I recently purchased a structure for my backyard on my phone.

In Poland it’s 33%

Poland seems to be 14%: https://gs.statcounter.com/os-market-share/mobile/poland

Ah, I stand corrected. Not sure where I found that high number.

In Romania it's 24.7%

Huh interesting, I missed that. You’re right (actually I see even 25.5%).

This sounds like every newcomers to the stage except for big players like Apple.
