The Game Boy was big, chunky, and didn't have the highest specs on the market. Yet its lack of a backlight and color graphics ironically meant it became the most successful handheld machine of the 1990s because it didn't eat up batteries like the Atari Lynx, Sega Game Gear, or the TurboExpress. Even so, it eventually had to get with the times. If it couldn't be backlit, it had to at least get color graphics.
