Well... Last week flying home in first class I did some unintentional people watching.
Before the whole cabin had boarded, there were 6 people I could clearly see from my seat. Every one us were looking at our phones, and every one of us had an iPhone X.
I even texted a friend cause it stood out to me as funny and a rather high percentage. After thinking for a second, it made some sense that folks in first class would have a higher likelihood of owning the latest and greatest. The 6 of us were definitely younger though than the typical demographic I see in First, which I think made a big difference. Estimated ages were prolly 27-45 when 60+ or at least 50+ is more the norm.
Still 6 iPhone Xs in 2 rows and within 5 sq feet of each other was as many as I've seen outside of an apple store...
