I seriously want stock Android on a high end device. Straight from Google's idea of what a phone should be seems like the best way to go. GIVE ME S'MORE Marshmallow!
The Nexus 6P is best phone out this year IMO. I would like to have 6.0 on a Nexus device with a big screen, since AT&T is holding back the update for Nexus 6 users.
I want a 6P to replace my once awesome but now crappy Note 3 (the upgrade to 5.0 ruined this phone). I'm really looking forward to the new camera. The Note 3 sucks at low-light photos.
