Got a potential laptop theft problem (and really, who doesn't)? You'll need some sort of lock - a solid piece of steel with a rubber-wrapped steel cable that'll foil a potential thief long enough for you to come back, interrupt their deviltry and brain them over the head with a metal pipe. Of course, if you're away from your computer for a while and someone particularly stealthy and resourceful breaks in, a lock may not be enough: you'll need an alarm, too, or so Belkin would like you to believe.
Their F5L013 USB Laptop Alarm breaks the standard lock mold by basing their security system around what appears to be a solid lock-like base with an alarm system and a USB cable. Cut or disconnect the USB cable and the alarm goes off until you insert a key into the base.
We have a feeling this alarm won't be particularly effective unless someone tries to steal you're computer when you're nearby - or have a particularly conscientious neighbor – but since it's USB based, we have to wonder: can you change the default alarm with tones of your own? We think "Step away from the computer. You are too close to the computer. " might be a good option to try.
