Great thread and exactly the question I had. Over the holiday (Dec 2014) my Razr M finally died (let the stupid KitKat update go through finally and it bricked). On a whim I called Motorola and was shocked when they sent me a free replacement M. I'm not loving the KitKat, nor the loss of root (really, it's killing me) but I'm living with it for now. Are there really no new phones in this size range? I've had my hands on all the phones at Best Buy and tbh the only one that felt good was the iPhone 5s, but I'm not willing to enter that ecosystem just yet. The nearest android phones I've found dimension-wise are the S4 mini (or S5 mini, but not picked up by Verizon yet?) and the Droid mini, but both of those are 2013 phones, I think. I saw rumors about a S6 mini for summer 2015, but what are the chances of a US carrier picking it up? Anyone have any thoughts/suggestions?
Edit: The features that I'm looking for (in order of importance to me) are: 1. Size, 2. Root user capability, 3. Speed, 4. Camera. Screen size/resolution are not important to me at all, but seem to be the things that the current gen of un-pocketable phones are pushing.
