Re: Mine has just been delivered
Just had mine delivered a day early, too. Great stuff.
Here's some quick thoughts (hope OP doesn't mind a small hijack):
1. I got the black one - the material is soft to touch, but not in the same way the original N5 was. The N5 had a grippy kind of feel - this material feels more solid, but silky smooth to the touch. I like it. The edge material is the same as the rear material too.
2. The gap between the glass and frame seems a lot tighter this time - I'm hopeful that there won't be as much dirt finding its way into that area as with the N5, for those of us who don't use cases.
3. The dimensions are lovely. I've come from a Nexus 6 and this just feels so much nicer to hold. Slim and light are the words that fit best.
4. Nice to be back on an IPS too - I prefer the more muted colours. It is as good as the N5 screen. The increase to 5.2" doesn't have any impact on the sharpness as far as I can tell.
5. The buttons protrude a nice distance and have a good clicky feel to them. They don't feel as sharp around the edges as they did on the N5. Small amount of rattle if that sort of thing bothers you.
6. The Nexus logo is printed instead of being inlaid. The logo and fingerprint scanner ring are a dark grey (graphite?) colour.
7. The fingerprint scanner is fast and reliable. It gives a single vibration for a successful attempt and a double for a failed attempt. Just touch the scanner to activate the phone.
8. Camera opens quickly and the auto-focus seems reliable and rapid. Haven't got much more to say about the camera yet.
9. The OS feels slightly slower than 5.1.1 on the N6. Very smooth, but more delibrately paced, if that makes sense. I wonder if that's more Marshmallow than the hardware - particularly as this benchmarks in the same region as last year's N6.
10. Ambient display seems to work at least as well as my N6 - although it's early days still.
That's all I have for now. It's a good start though and exactly the phone I wanted last year.
