To add to that. My son got his phone caught in a reclining chair without realizing it. The fact that the phone bent in half instead of destroying the chair is a nice bonus. Replacing the phone was cheap, replacing a chair would not have been — yes, both are insured, but replacing/repairing a chair takes a hell of a lot longer.
And for just a few bucks per month, it can be insured and replaced for a couple hundred bucks. My chair is also insured through homeowners insurance (the US equivalent name, called something different here in the NL), and they would give me the value of the chair… but now I have to find it again, get it delivered, take my old chair to the dump, etc. The phone was a quick visit to the Apple Store and restore from backup.
