I bought myself the Sapphire Blue as an Xmas present and really enjoyed it. That said, it was a 32GB and bought at Best Buy (they had them for $299). And then came along Amazon, and I was so happy to see the Black available. So, I returned the Sapphire Blue and waiting for my 64GB Black to arrive on Friday! Woot! Black is absolutely gorgeous!
All in all, when I used the phone for a day, I really enjoyed it. I struggled with the notifications but once I tweaked it, it was OK. Can't wait for the Nougat to solve this the right way. Been used to high end smartphone screens like iPhone 7 Plus, S7 Edge, I felt a little odd using the Honor 8's screen, mainly due to its bluish white tint. But for the price you pay, its OK. Display is not bad, its just not the best out in the market. The eye comfort option is fantastic though.
Fingerprint scanner is slick. Its super quick and love the smart key options. Not to mention how useful the knuckle gestures are. Many may call it a gimmick, but it actually works way better than a 'gimmick', that is, they are very productive.
