Potential places where you could be harassed for having assorted gadgets in your possession, with the risk of the gadget being confiscated:
High security workplace
Yep, that just about covers it. WRONG! Add to that list Alton Towers theme park in the UK, where 'special wardens' will be watching to see if you are using a Palm, iPaq or other PDA or smart-phone while on their premises. If caught, these special wardens confiscate your device.
If you're getting tired of this nonsense, raise your hand.
