What i didn't like about the XMp3: when playing back recorded content it didn't count down how long the recording was (say you recorded 4 hours of Stern) there was no way to see if you where an hour into the show or not. No bookmarking. If you turned to live xm or other recorded content, or turn it off, etc you couldn't come back to recorded content of where you left off. You have to start over.
Taylor, I want an XMP3 to replace my sl2, but I use my sl2 primarily to record stern shows and listen at work or driving in the car. My question is why do you say the sl2 is better for recording your favorite shows than xmp3?
Probably bookmarking. With the XMp3 if it goes into full, battery saving shutdown, or you switch from recorded to live, it tends to forget where it was in your program. So as long as you can remember where in the show you were (remembering the PAD helps) it's not really that much worse.
