Simple, foolproof rule: When you're away from home, always keep
your laptop in view even if you think it's in a secure room.
If that's not possible, use a cable lock to secure your laptop to
a table leg or a heavy chair ($30 to $80, www.kryptonite.com for
store locations). "If someone just picks up your laptop and walks
down the hall with confidence, no one's going to look twice," says
Broadway stage manager Patty Lyon, whose untraditional work
space a theater makes laptop locks a necessity. "It's the
equivalent of the Club for your car," she says.
