but then again, I’d say that’s probably specific to which app somebody is using or what site venue is causing the crashes.
That would be my guess as well.
My iPhone 7 (it's my work phone) has been great on iOS 13. No stability issues to speak of.
Hand gestures and Face ID take your phone to an enhanced user experience.
For me, that's not the case, but completely understand your preference.
Hence my Cassette tape reference, you can still listen to music, it’s just a different interface.
That's very true. Though like the cassette tape, they both work to this day!
My guess (referring to the OP): the iPhone 7 will be usable for at least 2 years (with at least 1 iOS update, if not 2. Believe it or not, you can use an iPhone that's not running the latest version of iOS).
Usable is the key term here: What I define to be as "usable" will differ from others. For me, if you're looking for a phone that makes calls, texts, browses the web, takes photos, video recorded etc, and you're not anal about having taking the best photos, having the fastest web browser, rendering photos the quickest, the ability to play all games (if you play them) at the highest detail setting etc etc then the iP7 is fine. If your needs are greater (ie if taking the best photos you can on your phone, or rendering photos the quickest, or you wish to use faceid and the swipe interface) than you're best served by replacing your phone and getting something newer.
