The blogosphere is abuzz with speculation surrounding the alleged 1928 time traveler seen talking on a cell phone in Charlie Chaplin's silent film, 'Circus.' I have but one question: What kind of phone was this 1928 time traveler using?

In all seriousness, retro revival has devices blurring the lines between decades left and right. Charlie Chaplin and the entire cast of 'Circus' (including the 1928 time traveler) have nothing on this list of old school gadgets.
