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 ;-)
Thanks or that, I do hope they come through with something at least reasonable. Being able to run i1 without Rosetta in SL would be a plus as well. From what I gather from the emails I got from X-rite, they must be dealing with a lot of grumpy owners of legacy products these days.
