Apple hasn't done enough to make me want to upgrade from my 6S . Should I break/lose my 6S, I may even replace it with another one and pocket the price difference between the newest models. Many of the more interesting features are in the Plus sized phones (cameras), which I'm just not in the market for. My pockets aren't getting any bigger no matter how many features they add, and I'm not convinced the iPhone X will be a UX improvement over Touch ID yet.
