I've had nothing but good experiences with BB's Service Plans, for 15 years. Free battery replacements, swapping products to the newest version of the device or just plain getting all my money back in store credit to buy something else. Being backed by an insurance company means that if Best Buy goes under (closes down) you're still covered to the end of your contract by the insurance company for the extent of what you paid.. last I checked AIG covered Best Buy. Huge insurance company, you might want to look them up.
If Apple just happens to close down (not that it ever would, but for the sake of this exercise it does), your AppleCare is either null and void or Apple has an insurance company backing them too who will cover repair of your item.
One or the other. I can't seem to locate an insurance company backing Apple though so I can't confirm which it is. The AppleCare fine print states nothing. I really hope that there is coverage if Apple happens to go under though.
So yes, I repeat. Your ignorance astounds me.
