Sharp eyes have spotted Delphi's upcoming SkyFi3 portable XM Satellite Radio. By far, its biggest attention getter is the fact that it has a microSD card slot, letting users store up to 500 songs and 10 hours of XM programming. There's also a 30-minute replay feature, so in case you want to hear a song that aired 25 minutes ago, you're in good hands. The microSD card slot means that the SkyFi3 is the first portable satellite radio with removable storage. You can just hear the RIAA's lawyers packing their briefcases.
