In fairness, 4.7 inches is now a very small phone. So small in fact that you have basically no options that small in the Android line, and no recent iPhones that small either, if I'm not mistaken.
As a lifelong Android user, I'm very grateful that this exists. I detest just about everything about the Apple ecosystem and dislike the design of most of their products I've tried, but I will be getting an SE next time I have to get a new phone unless Android has responded, simply because that's the only way to get a quality phone that small. Even if it means giving up Firefox, for example.
