The Pioneer Inno portable XM2go ($400; available Q1 2006) combines live satellite radio and MP3 playback in sleek portable package. It has a time-shifting memory mode to store up to 50 hours of XM programming, a built-in wireless FM transmitter that beams XM to any FM radio, and a clever feature that allows you to "bookmark" songs heard on XM radio, connect the Inno to your PC and then buy the songs online from Napster.
