unpopular opinion: the iPhone 4/4s (flat glass back sooo aesthetically pleasing, i’m tempted to just go out and buy one now regardless of how ancient it is simply for its beauty) followed closely by the 5/5s/SE (especially my current phone, the rose gold SE 😍). I just have a strong preference for the boxy looking phones and much smaller compact sizes, they are literally the only phones I can actually fit in my pockets and comfortably use and carry around in one hand. If I need a bigger screen I have a macbook.
I’m probably upgrading to a new 8 or rumored SE soon and i’m excited for the newer features but not looking forward to the large size.. though there isn’t really a choice at this point. No ones ever going to make a small phone anymore at this point :/ that ships sailed. I might either use my SE for music/gym or sell it and buy the new ipod touch instead. Last year I briefly had Huawei phone the same size as a 6/7/8 iPhone and it just wasn’t comfortable enough for single hand use while listening to music or exercising, and it’s features weren’t much of an upgrade so I ditched it and went back to my SE lol
