Just launched in Japan, the WonderSwan was Gunpei Yokoi's next system after creating the Virtual Kid for Nintendo (he also created the Game Kid system and the Metroid series). The initial WonderSwan features a monochrome display screen and was designed to be played either vertically or horizontally. Games varied on this aspect, with a wide range of games. Plus it operates on simply one AA battery!
