Look poor (Score 1)

As someone in the same position I take my laptop around in a dull outdoor rucsac whilst wearing a fleece and jeans and don't look like I'm worth mugging.

Another idea is to put personal/private/important data on a laptop onto and only onto a USB pen drive hidden in tiny pocket where muggers won't find it, cos equipment can be insured/replaced but that data must only be in your hands.
