An in-flight entertainment (IFE) system that integrates a touch screen display device with a tray table (e.g., an airplane tray table or a train tray table) to provide a superior media experience. The IFE system is configured to be situated in an active use position wherein a user may interact with the touch screen and also use a tray table. The IFE system may be moved into a stowed position wherein it is positioned adjacent to a back of a passenger seat and operated in a passive viewing mode. The IFE system may include a bottom panel or tray portion having a window pane so that the display device is viewable when the IFE system is in the stowed position. A portable IFE system comprising a foldable clamp that clamps to an edge of a conventional table and folds into a stowed position is also disclosed.
