MyFiIf you're an XM Satellite radio fan, you'll be happy to hear that Delphi and XM's MyFi, the world's first Walkman-style satellite radio, is now on sale. MyFi streams XM's 130-channels and records up to 5 hours of programming on its 128MB drive, enough for you to walk the dog around the block 600 times. Of course, you have to be a really BIG fan to pony up the $350 bucks for the radio, plus the $10 monthly subscription fee—we'll wait to see if version 2.0 is cheaper and has more features (like being able to transfer songs to your PC and vice versa), and is bit less, um, fugly.
