....A BIIG difference: PegasosII will use faster, cheaper and easier to find DDR Ram modules, will have Gigabit Ethernet interfaces (maybe 2) and a faster bus (actually it runs at only 100 Mhz :-(((). The last and maybe most important thing it will no use anymore the buggy Articia chipset used also by AmigaOne/Teron but the new Marvell. :-)
