Ten years ago, I stood in line to purchase the wonder of the age. My spouse declined, her flip phone was enough. That evening, as I played with the first iPhone, she decided we'd made a terrible mistake. We were back in line the next morning.
Those phones maxed out at 8 GB, one color, and only worked on AT&Tingular. No third-party apps, 2.5G Edge service, no front-facing camera, and so on. Yet they were still a marvel, years ahead of any other.
Now, a scant ten years later, comes miracle and wonder that fits into your pocket. The number of features and improvements in only ten years boggles the mind and would fill more pages than you want to read. Just a single example: The cameras have gone from showing what is there to now showing what is not there (Animoji and Augmented Reality).
Can another mobile do this? Probably, but another mobile device doesn't run iOS. It doesn't automagically sync all of my phones, my songs, my desktop, etc. to itself. It doesn't protect my privacy.
So include me as someone who is dumfounded by people complaining that the latest advances in the most revolutionary tech ever developed is somehow disappointing because it doesn't come in peppermint.
