I use an iPhone 7 for my personal phone and a BB Priv for my business phone. I'm planning on purchasing a BB KeyOne when it's available in U.S.
I got to play around with the KEYone for a few hours and it's a pretty awesome phone. The physical keyboard took some getting used to for typing, but using it for scrolling or button press for app launch are amazing features. The build quality is also surprisingly pretty awesome to me, I would never use a case for it because it feels very durable.
