Nice responses gentlemen, thank you. As well as my BB10 phone interfaces with my iPad 2 via "Blend", I am more than willing to give this up for a total iOS experience. And to me, it's not the Apps. I have enough apps on BB10. It's the way iOS just glides. It's always been the most elegant OS and that trend continues.
But really, the final decision-point for me was Apple Music last year. Music is such a huge part of my life. Truly. I've tried all the MAJOR streaming services. Apple Music is, to me, the finest out there. And the fact that it is built into the OS of an iPhone and not running as an outside App? Incredible. To me, this was the final blow. I have to jump on board with an iPhone. I have no other choice. So the old (but minty) 4s has the SIM back in it, I have put on a battery case so the phone lasts all day and then some, and I carry it with my iPad2 (also in mint condition). The screen of the 4s is a bit small for me, but it will do until the iPhone 7 debuts in September and I either get a new 7 or a new 6. I am running iOS 9.2.1 so I won't be totally lost at all jumping to iOS 10.
