I had assumed that the OP was using the laptop for work purposes. At our location, personal laptops are, well, not banned, but not allowed to be hooked to the network, and there's no wireless within a mile, so there's really not much point in bringing one in.

Hooking up flash drives and other storage is OK though. And many people have work-provided laptops (lots of them travel with them).

So it depends on the purpose, and the rules at the employer.
