Yep, I can see all everyone's point about this. I am not saying it won't be different for people. I just know in my family situation, Me and my better half have iPhones 6s (mines a plus and hers is not). She also has an iPad Air. She will never use both at the same time and she will always have her iPhone on her, even with her iPad. So, it only made since to get the non-cellular model. Once I showed her how to tether her iPad, she was tickled pink. Also with the amount of time she uses the iPad tethered to her iPhone is only when we are on the road, I am not too concerned about battery life on either device. I do agree there are going to be cases where you want a cellular version of a tablet, but to me, it's just a waste of $120 a year, but not to others, and that is cool. Just thought I would bring it up.
