Hmm... This thread is making me realize that I currently don't have the "protection plan" simply because I couldn't afford it before but, now, I rely on my phone for LOTS of things (heck, I can even remote in to servers and fix 'em from the dang thing!) so maybe I should add that to my plan.
My current cell phone has replaced: My home phone line, a separate navigation device, taking an iPod with me, taking a camera with me, my alarm clock, having to take a physical game or book, my desk calculator, taking a flashlight with me, etc. I have reference material in it, I learn new things on it, I keep client information on it, my grocery list is there, any to-do lists or spontaneous notes (I have a Galaxy Note 5 with that wonderful stylus). Plus I'm sure I'm missing other stuff. It's great!
Now that many of the "nice to have" things are far more stable and accurate (like the GPS navigation and camera/video resolution), it really has become a valuable, go-to tool for me.
Of course, in the last 15 years, I can count on one hand the number of times I've dropped my phone or temporarily lost it (and still have fingers left), so that helps! The new wireless chargers are wonderful (and, if you get the Galaxy Note 7, you can start campfires with it too! LOL).
