I sympathise with your plight, I really do.... however, you bought the thing to be a mobile device, so how was using it on the bus stupid....If the only place you are prepared to use it is in the safety of your own home, why buy it in the first place? Yes it is bad when it happens, but seriously... if you are afraid to use it in a public place, what is the point... this stuff happens, and granted it is not nice, but keep your wits about you... dont sit near the door, etc, and avoid this kind of thing.... Dont let these bastards win....
