Oh, sure, but I still thnk striking down with great vengeance and furious anger upon those who remote-wiped your devices would be justified, even with backups. If nothing else, it costs time to restore from backup, but if you were on a trip or something and had no convenient high-speed access to backups, it would be quite unpleasant. Especially if you had, say, iPad iPhone MBA, and assumed at least one of them would be likely to survive the trip, and thus had no other local backups with you.

But yes, backups -- and not just online backups, but also offline backups.
