With regards to purchasing extra insurance, on any item, it's a gamble. As a former car salesman I can tell you, there's no right or wrong answer. The added insurance is great to have it if you need to use it. I use AppleCare+ because you never know. Doesn't matter what case is on your phone, or how careful you are, accidents can & do happen. It's come in handy for me in the past, but that's just me.
