Nintendo has unveiled a smaller version of its portable double-screen DS console dubbed Lite and introduced services that might attract users interested in more than games. The new model, to be launched in Japan in early March, measures 133x73.9x21.5 mm and weighs 218 grams. Additionally, Nintendo expects to launch an Opera browser developed for the console in June, costing the equivalent to USD 32. Users will be able to see any detail of a site on the top screen and the traditional window on the lower one. The company has also unveiled plans to offer a digital TV tuner card by the end of the year.
