Anyone wanting to do serious typing on a PDA or Smartphone needs a decent external keyboard. Even though thumb keyboard aficionados may beg to differ, I believe they will agree that no one can thumb 60 words a minute, even 40. Think Outside, Inc., a small company founded in 1998, designed the very popular line of Stowaway portable keyboards and mice which are included in the Design Collection of the Museum of Modern Art (MoMA) in New York. In May 2006, Think Outside, Inc. was purchased by Mobility Electronics, Inc., the makers of the versatile iGo power adapters. In September, Mobility Electronics released a new full size foldable keyboard based on the Think Outside design: the iGo Stowaway Sierra Bluetooth keyboard.
