Lockdown your Mac

Laptop theft is rarely an issue for me. When traveling, it is rarely far away from me, unless it is back in the hotel room and safely hidden away. But there are times when I need to leave it unattended for a time in a public place now and then. For those times, it is nice to have an app like Lockdown (formerly iAlertU) which provides a simple car-alarm-like interface for your Mac. You can set it to trigger when the laptop is moved, when power is unplugged, or when other operations occur. You unlock it with a simple password - chosen by you. It can even e-mail you a photo of whoever tried to take the device.
