Nintendo unveiled it new gaming console, Game Boy Micro, which has the same size as a mobile phone.

At 4 inches wide by 2 inches long by 0.7 inches tall, it's just a bit larger than an iPod mini. According to Reuters, Game Boy Micro attracted better-than-expected orders on its debut on Tuesday, though less than Game Boy Advance SP had done.

Nintendo, known for software titles featuring characters such as Mario, Donkey Kong and Pokemon, launched what it said was the world's smallest console in Japan a week before the U.S. launch with a price tag of 12,000 yen. ($109)

The Game Boy Micro, according to Nintendo, is being targeted to the mass market consumer - young adults between 25 and 35. Though Nintendo would not reveal the total amount of units shipped to stores in Japan, the company reveals that it's on its way to sell four million units worldwide by next March.

The Micro is available in Japan in silver, purple, black and blue, with a fifth "limited edition" design in the color of the once-popular Famicon game console aimed at attracting adults who played with the Famicon as children in the 1980s.
