My Nexus 5 came in the mail today.

I honestly wasn't planning on getting one so soon, but then my end-of-year bonus came in from work, and I was like, ah... to hell with it. So I pulled the trigger. I also ordered a new AT&T MicroSIM from Straight Talk so I can take advantage of the LTE connectivity. This is my first LTE phone.
I am very pleased. Coming from a Galaxy Nexus, it's sublime. Everything is better. The screen is better. The camera is better. The battery is better. The software is better. The performance is, all-around, better. The few things that my Gnex choked on are now handled by my N5 like a breeze. I could go on listing everything, but it would be a waste of time because literally everything is an improvement.
Well, maybe not everything... if I had a gun to my head, I'd maybe say that the speaker placement isn't great. It makes sense to move it away from the back and toward the (bottom) side, but even then, I often find myself placing my fingers underneath the bottom edge of the phone, and wondering why I can't hear anything. Also: The vibrate feels a bit cheaper than my Gnex. Like it looks and feels a bit more "rattly". But I'm nitpicking at this point. Those are two small cons up against a huge list of pros.
I love the phone's design. Very modern, very aesthetically pleasing. I wasn't a fan of the Nexus 4; too round and sparkly. But the Nexus 5 hits all the points I like: It's more rectangular, more simple and subdued. Love the matte black backing. I think they did a great job.
Previous posts in this thread made me worry a little about the color, but it looks good to me. I compared the fully-saturated red image on my phone to the image on my computer screen, and they look pretty darn close. Computer monitor version looks a tad bit brighter, but I know my cheap LCD monitor is a little bright and not really calibrated anyway.
Anyway. For what it's worth, here's the first picture I took with the camera. Not ideal lighting conditions, and not really a formal test, but man it sure is a step above the POS Gnex camera.
