Long story, but after our experience in Dallas, we have decided we need at least one smart phone to replace one of our flip phones. So I need some advise from you savvy smart phone users. Because my wife has a iPad and an mini iPad, it seems her devices would all sync up, so we are leaning towards an iPhone. We have a friend who has an iPhone 6s plus that he will sell to us for $500. That doesn't seem like a "friend" price. I went to the T Mobile site and can get a 6s with a 2 year contract, for $785 total. It includes free data and time. $175 up front and then ~$28 per month for 2 years. So, let me hear some opinions.
