Thinking of switching from Note 2 to G4

The primary reason I'm considering the G4 instead of any of the new Samsung models is to gain root. If I order the G4 now and it comes with 12a will I be able to root the phone right away?

Thanks,

Anyone thinking of making the switch to Nexus 6P?

With slow updates from Samsung/Verizon combined with Samsung Pay that doesn't work with rooted devices, I'm contemplating whether it's worth it sticking with Samsung anymore. I originally thought Samsung Pay would be a game changer, but then it took months for it to be released and they have eliminated root users. The Nexus 6P seems to hit all the points for me without any restriction of root AND an unlockable bootloader. Yes Android Pay is not nearly as universal as Samsung's, but there's less bloat, immediate updates, etc etc. Reviews seem favorable.

Thinking of getting Fire TV Stick

Stationed overseas, looking at buying a FireTV Stick to run Kodi and other apps on it.

What are the pro's and con's of it?
What apps should I install on it?
I have a ton of movies/tv shows, could I stream from my iMac to it? (This isn't needed to much)

I've had Kodi before on my devices, so figured a FireTV Stick would be a cheap alternative to have it on my Sharp Smart TV.
