I am actually really loving the Nexus 6p. I find android to offer me more, such as google now and how it tells me time home, puts emails for appointment right into my calendar, saves where i parked, etc. The app gap isn't an issue to me whatsoever and I found some apps to actually be more feature rich somehow? For example, theChive had way more posts on the android version with them nowhere to be found on iOS. As far the camera went I found it to be on par if not better in some situations. They each took better pics in different environments. Video was definitely not as bad as you say as I have an iPhone 6s (not plus so I know the OIS makes a difference). The display is fantastic and has front facing speakers and still manages to be the same size as the iPhone 6s plus. With apples design chops how in the hell have they not figured out smaller bezels? I absolutely love the finger print sensor and find it quicker and more convenient to how i actually pick up my phone. Yes on a desk it is not accessible, but google being awesome you can set up secure locations where it can be bypassed, such as the office.
The only reason I may not keep it is because apples stupid "locking in" and close mindedness. I cannot as easily share photos, reminders, and calendar events with my wife using her iphone. I do like having the ability to very easily share calendar events and photo albums with her and my family. Oh and facetime. My grandparents can barely figure that out I can't imagine the nightmare having them have to sign up for skype or something else...
Other than that I would say its the best android yet and I just came from using the note 5 on the trial. I like this better as I get the latest and greatest updates, security, and heres the best part this phone at 64 gb is 300 less than the iphone 6s+ and the only thing we can knock is videos aren't "quite as good". Thats ridiculous that apple gets that premium for having 3d touch and OIS...
