You can record from any stereo source with a stereo in-line jack and won't have to get any specialized software to put recordings back on your computer--all you need is an analog or digital source at bit rates up to 160 kbps.
Starting with the base, the back side features inputs for power, a 3.5mm line-in jack (sadly, you can't bleed in your PMP with the TOSlink feed), an optical input and a sync button.
