The step from Model 2 to Model 3 is enormous.... Model 3 to NAOMI is a slight upgrade across the board.
Hikaru blows away NOAMI in some aspects and is a slight downgrade in others... it's really an oddball piece of hardware. I believe it was actually developed BEFORE the NAOMI but was abandoned quickly because of the cost. I could be wrong.
