I've gotten numerous emails from X-Rite that they will be providing this update free of charge to registered (that's REGISTERED) owners of some devices, including the Eye 1 Display 2 (which I have). They must have your serial # on file.
I remember mentioning to them about 6 months before Lion shipped that Rosetta wasn't a default in Snow Leopard. Guess 2+ years later they got their hand forced ;-)
