As far as I can tell, the pen for "Seiko Smart Pad, Cross Pad, IBM Transnote and Decrio" probably does not work. I didn't find any reference to Penabled in any of the device descriptions. I did find several places describing the pen as requiring batteries. The Penabled pens are powered by the radio field from the tablet, so it's highly likely the pen you're looking at is not compatible with the eDGe.
