An anonymous reader writes "VIA has decided it’s time to update the APC (ARM PC) board with new components and the choice of two configurations. The new systems are called APC Rock and APC Paper. The hardware spec for both boards is exactly the same except for the fact the Rock ships with a VGA port where as the Paper doesn’t. The Rock also costs $20 less at $79, where as the Paper is $99.
The reason for the price difference is the fact that the Paper ships with a rather novel case where as the Rock is a bare board. The Paper’s case is made from recycled cardboard attached to an aluminum chassis to help with strength , meaning it will keep the dust off the components and make it easier to carry while keeping weight to a minimum."Link to Original Source
