Honestly, 4.7" is probably "small enough" for more people. I had a Nexus 6 and switched to a Moto X when that died, and at 5.2", it's much better. I would prefer another inch or so smaller, but honestly a 4.7" might just be good enough to be comfortable.
That being said, I miss the days when small phones were all the rage (e.g. like in Zoolander). My phone needs to be just big enough to use GPS and basic web browsing (i.e. look up a menu for takeout), and that's about it. I don't need to watch videos or play games (in fact, not being able to is a productivity feature), I just need a simple phone. It seems the "do all the things" market is well served, but the "do only important things" isn't. I just want something in between "smart phone" and "dumb phone" that can fit nicely in my pocket and hand.
