I have two retired 4s phones that I use for making videos and recording music. My wife has a 5s and I have the 6s. I also have a couple of retired i-Pods but I never use them. I also have 3 different brands of Android tablets, a chrome book, a net book, and a laptop. About the only thing I don't have is an I-pad.
Okay, my apologies as you indeed have a 6s. Others in my family have iPhones, although my wife and I do not. We have been using TracFones for years, they get the job done for us cheaply and anonymously. But we have iPads to fill the gap, mine has 3G. I have several old iPods. I have a number of accessories that fit the dual ports on top, half of it is a mini-jack. Among them is an FM radio, another is a mic with switch, mini-stereo speakers, etc. I felt bad when Apple dropped the dual-port feature on newer iPods, but progress is progress. I could no longer use those accessories with newer iPods or the iPad. However, the iPad had functions which made those older accessories on the iPods obsolete. I listen to radio stations from around the world on my iPad, far better than just pulling a few stations from off the air broadcasts. Stereo speakers built-in, same goes for mic. I rarely use the iPods any more. I like vintage gear, and have collected a lot. However, I enjoy the newer technology much more. We're looking at buying the iPhone 7 to replace our iPads. My wife has used hers since 2010 and is ready to move beyond that, same here, to better keep up with our family members.
