The original Game Boy Advance fits comfortably into the pocket of a backpack. The retooled Game Boy Advance SP fits into a coat pocket. Now Nintendo takes aim at the pocket of your tightest jeans with the tiny Game Boy Micro system, quite simply the smallest and sleekest Game Boy product that Nintendo has ever created. It's thinner than a cell phone, as chic as an MP3 player and as fun as a Game Boy. In an instant it attracts attention and positions the image-conscious player as someone on the cutting edge of cool.
