I am discussing getting things done, quickly, easily, rapidly with maximum efficiency. What are you discussing? Bending around your phones inherently limited architecture? Oh, yeah I can answer a call from any device anywhere gave been able to for a while.Are we talking about phone or what? Try putting your sp4 in your pocketWhy stop there. Why not bring along your macbook as well.
Your "ability to answer call" from any device is inaccurate. Should be from ONLY apple devices. With Samsung Flow or Air Droid, you can really do that from ANY device. Since you are already carrying stuff along, doesn't hurt to carry the apple TV with you as well to do mirroring.
S8 can do all above by itself without lugging along any other devices. Much cheaper too.
Try tackling a major client issue that requires a real computer with your s8. I do bring along my MacBook always with me. Oh, and I can answer a call on that also.
I've played around with the s8 and Imo the "average" iPhone user will stay with Apple.
