Uh, no I didn't ;)

Look, the thing is, if you're worried about a casual thief, they probably don't care about your data anyway, they're going to wipe the device clean and resell it. If it is someone that actually stole the device to get the data, then I would expect your '1%' (plucked out of the air, or is there a reference for this kind of statistic - honest question, I'm not snarking) is actually going to be a much higher number, in which case the encryption isn't going to save you. It's pretty much game over once the attacker has their hands on the physical device, afterwards it's just a question of time.
