In our list of behind-the-times tech in Hollywood movies, we missed a classic: Little Black Book, a Brittany Murphy vehicle which centered around a girlfriend discovering her boyfriend's PDA.

Palm Pilots were the epitome of cutting-edge cool — in 1998. By 2004, when the movie came out, the PDA market had entered terminal decline, as people switched to keeping their contacts on increasingly advanced cell phones. And the best part?

Sony, whose movie studio released the film, exited the PDA business in early 2005. Not that electronics executives at the famously combative conglomerate would have ever tipped off their counterparts in Los Angeles.
