First, the N5 is an awesome phone, especially compared to my previous phones. However, just one little quirk: the OK Google voice commands are not "learnable" a la Moto X. I like being able to use OK Google, but the prankery gets old. And too tempting for me. Anytime my phone is on the homescreen, my wife can blurt out "OK Google" and now I've got to close it before she tells it to do something else. And the same vice-versa since she has one too. Think there might be anything in the works from Google to allow it to learn my voice? I'm really glad they didn't do something like have it always listening AND not learn my voice. The pranks would be maddening (thinking of the "OK Google Find My Phone" command in particular).
