Dumb quote of the day: “If it works, the XM Radio portable is a much bigger deal than the latest iPods. Think about it, just about everybody listens to radio, while only about 60 percent of the U.S. buys any music at all,” said Jupiter Research analyst David Card from an equally dumb article. Radio is everywhere because it is free. XM MyFi costs $350 and $10 a month. Or about $120 a year. Expect a nice write-off from XM in three quarters from now.
