The folks at XM Radio were kind enough to give me an XMP3, and I'm having a lot of fun with it, so the least I can do is tell you about this Christmas promotion they're running.
For starters, the XMp3 portable satellite radio is now on sale for $199. And, if you click that link above, you can get a free MicroSD card. There are other incentives too, so click here if you're interested.
