I switch between my 7 and X a lot. But the fragility of the X has me concerned that I'll drop it and either one side or the other will get damaged. Unless I keep it in bubblewrap. I get by with the little keyboard on smaller phones by dictating my texts with Siri. And my reading glasses help.
I keep my iPhone X in an Apple leather case with a screen protector and recently on a trip to Mexico I dropped it on a street paved with stones which was quite uneven. Luckily, it's not cracked, dinged or dented. Sadly, the leather case certainly is--but it's there to take the hits.
The iPhone X is smaller than the 6s Plus I was using and I really enjoy the smaller size. I can't imagine the 6.5 inch iPhone rumored to be coming out later this year. Might as well just carry the flat screen in your living room around with you.
