SolidAlliance has announced the "world's first USB memory with ghost detection." The "GhostRadar USB Memory," in addition to having a capacity of up to 512MB, features a magnetic field sensor, people-detecting sensors, and a biological clock. When the unit detects a ghost, a certain pattern will shine on the LED display.
Not that ghosts and USB memory have anything to do with each other.
