With the trend to make ever larger but thinner phones, we'll eventually end up with an A3 sheet of paper. I just want the 5/5S/SE1 or Mini form factor back. I don't care about thin phones, only about being able to use the whole screen with one hand.
Many features seem to come like 5-7 years late. Somewhere around 2016 Apple had finally added so many of the basic features to the iPhone that I could actually start considering it a realistic alternative to Android phones. Before that, there were always several serious deal breakers. Nowadays, things are actually surprisingly tolerable. It took like forever to get there, but now the phone actually does all the basic things.
