Thanks, Ramius. I use an iPad as well an iPod for those you listed.
The iPhone 5c would be my go-to for calls, but not so much for the other apps.
I checked out the Apple Pay (That whole Apple Live was a mini-disaster). I’m taking a wait-and-see with that.
The iPhone can be a mobile WIFI hotspot for your iPad, or your WIFI on a laptop, sharing data bandwidth. Works great.
