The Nintendo DS Lite is the best selling game system on the market. This handheld, which is basicly a revamped DS, caught the eye of people all across the world. This system has a wide game selection, inculding online play. The DS Lite has 2 screens. How is this usable? A great example is Mario Kart, when driving the bottom screen is used to see in front of you and the top screen is used to look behind you. The graphics aren't as good as it's competitor the PSP, but the price is.
