My history with the iPhone is - 3G - - 4S - - 6Plus - - X - - - -
The X has lasted me well, although the battery is understandably running down quickly now. I pretty much live by my iPhone, but I think I’ll opt for an SE if it is released next year.
My challenge is to see how I can go with an iPad Pro as my main computer, so the iPhone can afford to be smaller and not a high end model.
For what it’s worth, I created a poster of iPhone models for my nephew last Christmas as he was obsessed with iPhone history.
Here it is - in compressed format - thanks to Ken.
If you’d like the original poster (A1 size) send me a private message.
