But the real issue is whether the Xbox can take on Nintendo's Wii which is now the No. 1 best-selling game console in the US. And the answer is probably not. Why not? The Wii broke out of the tight confines of "young, avid gamer" category the Xbox and Sony's Playstation inhabit with new technology and experiences that appealed to a much wider audience. Old folks swinging virtual golf clubs, middle aged folks doing their thing all found the motion sensitive Wii fun and fantastic. Wii opened gaming to the entire population, while Xbox and Playstation stuck with the small segment of young gamers.
