Do you ever run into problems dropping it? I stuck with the Nexus line from the Nexus One all the way up to the 4, but even the 4 was too big for my hand. I could barely use it one-handed, and I believe that contributed greatly to me frequently dropping the phone (went through 2 screen replacements). Never had I had this problem with a previous, smaller phone. After the N4, I downsized and I'm much happier.
(I suppose that's also a thing: I want to be able to primarily use my phone one-handed. If you're consistently a two-hand user, I guess this isn't much of a problem.)
