This is what's killing me also. If you asked me for an ideal phone size in 2013, I probably would've said 4.5"-4.7". If you ask me now, I would say it's 5.0"-5.2", with minimal bezels. I absolutely hate big phones, and see no purpose for them. I love consuming media, but I don't consume it on my phone personally. I have tablets and other devices for that.
I'm not saying don't make big phones, but give the options to consumers for smaller phones. I want something w/ the power of Moto X in a Moto G size. They could have a new SKU: the Moto X+ which would have the same internals as the Moto X, but just a bigger display. If you have options, everyone wins.

I did receive my Moto G 2015 (aka 3rd. gen) yesterday, and it's a nice phone. I got the 2GB RAM/16 GB version, and for the price, it's great. The power user in me wishes it was slightly faster, or had a better display/camera, but I can't complain considering what it's worth.
