I have a razr with big external screen. I like open to answer and close to hang up, it's satisfying.
But I really like that when its closed, it is a nice little device when I just need a little device. Also nice to fit in pocket.
I kind of like the concept of using it as a stand or tent, but frankly it won't stay "on" Long enough for me to get that much use out of it, even when plugged in.
Downsides have been the battery not lasting as long, and once in a great while I pinch myself a little when opening it. Also if I'm trying to wirelessly charge it in my car while also doing Android auto it tends to overheat a bit, but doesn't when I actually plug it in.
