What Makes The DS So Popular?

Next Generation is running down the reasons why the Nintendo DS is so popular in Japan, by analyzing an article on the subject from Famitsu. From the article: "In any department store in Japan, there are DS demo stations. Usually the screens are scratched to high hell (I can't imagine what people are DOING with the stylus), and lately, there are a lot of games to choose from. On the launch day of Xbox 360, I recall seeing a line eight persons deep to play Super Mario Kart DS, and not one person even looking at the 360. This was in Shibuya Tsutaya, statistically the most foot-trafficked game retailer in all of Japan."
