I would imagine it is part of the standard boiler to cover their ass in court. They guarantee that the Wii will work with official software with the Nintendo seal of quality and all that. Once you use stuff that they did not make or approve, you are on your own. If you break something, it is your own fault.

It was a Zen Vision: M

The Creative player I owned had a proprietary AV-Out, no replacable battery, no flash reader, the USB port was proprietary, and the DC plug may have been relatively non-proprietary but I never saw a universal adapter with the proper voltage or the exactly proper sized plug.

In recent years they have stopped with the free stuff. All I got with my latest one was head phones and a USB charger. Wall charger and AV cables cost extra.
