I'll try to stick with the same formatting

Unboxing: I've never really been real big on the whole unboxing experience, but the set was well put together. Whats more important for me is what comes with it. In this case you get the phone, setup manual, SIM tool, a USB-C to USB-C cable, USB-C charger, and (TINY!!!) USB-A to USB-C Cable. The A to C cable must be meant for connecting to the PC, as its far too short for much else. I'd recommend people buy some more USB C charger now, or at least the USB A to C cables to replace the ones in your current charger.
Hardware - The phone is premium. I love the aluminum finish and the screen is amazing, as we could have expected with the newest generation panel from samsung. My absolute favorite part of the phone so far is the fingerprint unlocking. I wasn't sure I'd be big on it when I had it but now its so convenient I actually use a lockscreen PIN/pattern, which I usually went without before. Pull it out of your pocket, place your finger where it would normally be anyway, and the screen wakes up, already unlocked and on your homescreen. Coming from the Nexus 6 I appreciate the dual front facing speakers. They are loud and sound is clear even when up all the way. One thing I also noticed right away is the nexus 6P's vibration motor is much better than that on the nexus 6. Its not as loose.
My one complaint is the bezels are a little large. Making the phone long. I'll get used to it though. The narrowness of the 6P is much easier to hold one handed than the nexus 6.
Camera- This has lived up to the hype for me so far. Photos are crisp, clear, and the HDR mode takes shots MUCH faster than on the Nexus 6
Battery Life:
I'm an Ingress player, so battery life on any phone doesn't last long for me. With that said, Doze mode does wonders. Standby battery drain is essentially nothing when that is on.
Not much else to say, I love the device so far! Had it for about 4 days now.
