Some embodiments are directed to a holder assembly that includes a lower covering portion that covers and thereby retains a lowermost portion of a mobile electronic device, the lower covering portion being integrated with a rear of a vehicle seat. The holder assembly also includes an upper support portion that supports a top portion of the mobile electronic device, the upper support portion being integrated with the rear of the vehicle seat. The upper support portion and lower covering portion are configured to cooperatively: 1) hold the mobile electronic device in the orientation to enable a passenger in a rear compartment of the vehicle to view the screen of the mobile electronic device upon the mobile electronic device being manually engaged with the holder assembly, and 2) enable the manual disengagement of the mobile electronic device from the holder assembly.
