I am thinking of purchasing one of the adapters. But I will sell off some extra Mac stuff to pay for it first. I think putting into a Duo would be great. Make the unit even lighter than it is already. As to wearing out the CF card, it might be an issue if it was in your one and only computer, but for casual use in vintage computers, I'm not sure if it is a very big issue. Having different O.S.'s on different cards is another good option.
