If I lost or damaged my phone 15 years ago, the biggest inconvenience would be gathering up all my lost contacts off my mates and shelling out for a new Motorola Razr. These days, as much as I hate to admit it, my phone is my life, like an external brain. If I lost it, I would lose not just my contacts, but photos, videos, music, messages, documents and a calendar, essentially rendering me a functionless human being.
