Nintendo is refreshing its two-year old DS Lite handheld device with a new version that's thinner, has dual-digital cameras and will be out before the end of the year -- at least in Japan. The DS-i looks similar to the current DS Lite and is a little thinner because it doesn't have a slot for GameBoy Advance cartridges. The device's two screens are slightly larger at 3.25-inches instead of 3-inches and two digital cameras have been added. The outer camera has a 3-megapixel resolution and pictures can be stored on an SD Card for transfer to the company's Wii or a computer. It will launch in Japan on November 1 and will cost US$179.
