Those cost per usage stats(figures/estimates) ^^ are quite a realistic way of looking at the cost of the iPhone.
Or any phone.
I pay a tenner a month more to have my current phone (Honor 8) than I would to be SIM only, so about £120 a year, £240 for the two year contract or around 30p per day. It’s my main computing device when not at work, my sat nav, bike GPS, camera, stereo (via a Bluetooth speaker), Smart TV enabler (via a Chromecast), flashlight when I put the chickens away.
Bargain! Over two years, a £1000 phone only comes to £1.40 a day over two years, even assuming no resale value. I’d not pay it, but it’s not unreasonable.
