To be honest, in 2016 all the phones are more/less alike except to the diehards in the various camps. The point is that smartphones in their current form are a mature product at (or nearing) commodities except for maybe the highest end.
No one but Apple or Samsung are making money. As much as it'd be nice to have more alternatives, there isn't much need relative to the cost save to satisfy us loud fans. What else could MS have done without having spent the billions on the Nokia purchase? The waste is staggering.
I'm one of the "all-in-MS" people (WP, SP4, custom PC) but if MS doesn't do mobile again for a decade but when they do it's a complete game changer I'd be up for that. And I mean a real game changer. Like iPhone was in 2007. Anything short of that releasing yet another glass slab phone seems like a waste of resources. There's just no point. I hate the idea of only having Android or iOS, but my interest in phones as a gadget may have died with WP (yeah yeah not dead). If the next phone I get isn't WM then I'm just going to go with a commodity mindset and reserve my geek zeal for other things.
