I’m no expert but AppleCare seems priced highly enough that they cover butterfingers too. I’d expect regular insurances to charge much less for a similar service (except definitely not as convenient)
From that, all I can say is don’t break your LCD or logic board. Coffee on your keyboard or touchpad aren’t so bad.
AppleCare+ costs the same per year but requires an additional €230 for the base AppleCare coverage.
If I wanted one I’m sure I could find for less too. Smartphone insurance is not something new or rare.
