I just thought it was interesting that both Microsoft and sony are releasing their own MP4/MP3/PMP players, called the Zune and Mylo respectively and both look like MPX Players, take a look:
Zune:
MPX Player:
Sony Mylo:
MPX Player:
Alright they don't look exactly the same, but they are similar and both MPX players have been around long before the design for both Sony and Microsoft players were publically released.
