I am seriously contemplating purchasing an XM Pioneer Inno. It's a portable XM receiver and MP3 player in one sexy unit. It can hold up to 50 hours of songs, be they XM content or files from my own collection and apparently has a user-friendly interface. I can't decide if I want it bad enough to fork over the money +monthly subscription, but it is mighty tempting. I remember a couple years back when we had XM in our car I was dreaming of a portable unit like this.
