Sorry if anybody feels insulted by this, but are you people completely daft and lacking common sense?
What sane person decides, I'm going to put all my contacts and enter the passwords to my email, twitter, facebook, chat app, my bank app and everything else that requires a logon, in this little device I can carry in my pocket. If I lose it, or it is stolen, I don't care if whoever finds it has access to all my stuff. A thief can post whatever he wants to my twitter or facebook, and pretend to be me, sending texts to my friends asking to meet them somewhere and loan me some cash. The possibility of any of that happening doesn't bother me at all.
Really?! I suppose you leave all your personal papers in a neat stack on your front porch for easy access, too? That couple of seconds entering a passcode and dismissing a lock screen could save you untold amounts of grief.
