Another gimmicky USB 2.0 memory stick. The Nail holds 2GB and comes at a size of 9 x 3.4cm for $43.39. Leave a hammer lying next to it and you might get some attention from your co-workers. When they get too close, you know that no one will steal it if you also have your USB Guard Dog plugged in. With built-in sensor, Desktop Rex will growl if anyone gets close. He can also run on 3 AA batteries (not included) for $21.69.
