IGN has a first look for iRiver PMP-120. The personal multimedia player is power by linux and I believe the price will be cheaper than those which will use microsoft portable media center software.
IRiver Nordic has also posted the main features of the player on its site:
Connect other USB On The Go units and use them together without the need of an computer. For example if you have a digital camera with USB OTG, connect it to the PMP-100 and transfer the images from the camera to the PMP-100.
