I don't know much at all about the radio wars, but I can somewhat see the point in rooting for one side over the other in the console wars... Nostalgia, current/potential selection of games, and whether or not you agree/disagree with the direction the companies are heading in. Reasons 1, 2 and 3 are why I like Nintendo, and reasons 2 and 3 are why I like MS for instance. Format wars on the other hand I think are pointless... Not only has it been shown that most people don't care about HD movies, but the 2 formats seem to be virtually identical to an outsider.
