MyFi

The rumors were true! Delphi and XM just announced the MyFi, the world's first portable satellite radio. It isn't cheap—the retail price will be $349.99—but they did toss in some nice extras like an FM transmitter if you want to listen to XM on your car or home stereo (though obviously there'll be some loss in sound quality) and some built-in memory for storing up to five hours of programming. Coincidentally, five hours is how much battery life you'll be able to squeeze out of the MyFi before having to recharge. Should be in stores by the end of next month.

[Thanks to everyone who sent this in!]
