A typical developer is spending much less on a phone as a % of their income, whereas a typical iPhone buyer is spending much much more — to a surprising degree.
I certainly wouldn't, but a lot of iPhone users are. I'm not judging, I'm genuinely surprised.
When I was making $22K a year in 1996, I bought phone for $300, was that too much to spend on a cell phone too?
To a first approximation, no one buys their phone outright in the US and 62% of people replace their phone every 3-4 years (https://www.nevis.net/en/blog/how-often-do-users-change-thei...). So they are only spending .45% of their income on a phone.
Apple released a security update for the iPhone 5s released in 2013 earlier this year. There is no reason to replace your phone every year.
Again, it's just surprising and not a value judgement.
How many of those devices have been coalesced into one £1200 iPhone. I call that a result.
