This fits my life so well it's depressing.
Just switched from a Galaxy S2 to the M8 and don't regret my choice at all.
I wanted something more drastically different from my old phone and for whatever reason have gotten pretty bad reception with my last two Samsung phones (one dumb plus the GS2).
Get better reception with the same carrier and location, like the change up and build quality, and the lack of touchwiz before I flash a different ROM is enjoyable as well.
I'm happy with my choice.
