Miguel de Icaza notes that Apple's latest firmware update limits the iPod to Windows and Mac:

The new firmware will now refuse to play any songs that you legally own unless you use Apple's iTunes (which is only supported for Windows and MacOS)

Now, off the top of my head, I can't tell why Apple cares what platform an iPod is used on - which makes me wonder if this is Apple throwing a bone to the RIAA...
