A few stray thoughts on the 6P so far. These are mainly on the way the phone feels.
The 6P feels more premium than any phone I have ever used, and I have used quite a few. That's quite a feat considering it only costs $500. It feels meticulously crafted. There aren't creaks and slack in the buttons. Nothing feels hollow or flimsy. The chamfered edges remind me of the Note 4.
It feels great for a big phone. I loved the 6, but this feels way better. This feels easier to use. It has a weight to it, but it doesn't feel big for big's sake. It just feels substantial.
The screen is great. Haven't had a chance to check it out outdoors, though. I have no complaints. I'm not a spec junkie, but this seems as pretty as the Samsungs. It may not be.
The back is slicker than I had hoped. I don't use cases, but I could see how you'd want one.
Marshmallow is great. It's snappy. Beautiful. The animations are smooth. I know I say this every time, but I can't imagine using any of the skins for an extended amount of time. I've noticed that every time I try one of the Samsungs, HTCs, or LGs of the world, the first thing I do is try to make it more like the Nexus phones. Skins are awful. The limited functionality they bring, if they do at all (debatable), doesn't outweigh the fact that they are ugly and look like they were designed by children. There's a design language at play here and it shows. The jury is still out on Now on Tap. I forget it's there, so I haven't really tried to test it.
The vibration motor is second only to the iPhone 6+. The iPhone 6+'s vibration motor is insane. It's so hard to explain. I suggest everyone feel it.
The speakers are awesome. Nearly Boomsound awesome.
I really like the color. At first I kinda wished I had gone with the Frosty 6P. Not anymore. It's a great looking phone, but it's subtle. It won't catch eyes. It's primary purpose doesn't seem to be wanting to get people to ask you to use it a la Samsung's S6 series.
I like the LED notification light on the 5X more. This one is really subtle. With the 5X, there's no ignoring or missing notifications. This seems small, but for someone like me who hates ringtones and notification sounds, it's a detail I miss. I also liked the placement on the 5X more.
The bulge on the back is so small it seems silly to even be mentioning it. I wasn't as appalled by the initial leaks as some were (I liked the Droid X). I wouldn't have minded it even being more pronounced.
So far, I really like it.
