My history of smartphones is:
ZTE Blade
iPhone 4 8GB
iPhone 5 64GB (Got a good deal on a brand new phone shortly after the release of the 5S and 5C, cheaper than a 32GB 5C)
iPhone 6S 64GB (Refurbished from Apple, bought shortly after the 7 was released)
iPhone 11 256GB (Bought at release)
My wife's upgrade cycle is offset from mine, so we've have had many different generations in our household:
iPhone 3GS 16GB
iPhone 4S 8GB (was free with contract renewal, upgraded to 64GB when I bought a cheap busted model and did a logic board swap)
iPhone SE (2016) 64GB
iPhone 12 mini 128GB
