As any espionage operative will tell you, spying on someone's computer can a frustrating task. It usually involves loading software, which always ends up taking more time than anticipated--thereby increasing the chances of getting caught in the act.
That's why U.K.-based Spycatcher came up with the "Keywatcher," a small gadget less than 2 inches long that plugs into the back of the subject's computer, according to Uber-Review, not unlike a USB storage key. Spycatcher says the gadget, which goes for 107 pounds (or $215) holds "up to 65,000 characters of text (typically between 40 and 50 pages) which can be recalled by simply typing in a changeable password."
In fact, now that we're aware of this, we'll have to position one of our many surveillance cameras behind our own computers.
