Nexus 6P. So much real estate, so little time. Currently have a LG G4 and am starting to develop mental issues from having a locked bootloader. 6P=unlocked bootloader on Verizon.
I mentioned elsewhere, the Nexus 5X due to its design, size, and I love its minimalist look. That and I'm keen on its feel in the hand. I still don't "get" 6-inch devices, but maybe I don't need the largest, most vivid screen and resolution.
Great contest around the holidays! Either would be an awesome device. Currently have the Nexus 5. Not sure whether I would like to keep the size of the 5X or upgrade to the 6P.
I have been a Nexushead having owned the Nexus 4, 5 and both versions of the 7. Recently I have moved to the Samsung side with a S5, S6 and a Tab S 10.5. I'd be interested in trying out the Nexus 6P to see if I am ready to come back to the Nexus family.
