I would go over to Adobe, but I don't trust them either. Its difficult to explain to a casual user how important your files are wether they be still or moving, the time and money in my stock of images is £100k, I have to be so careful trying to future proof what I have.
Transferring many TB over to another system is not a five minute job, choosing Aperture was a commitment on my part, Apple promoted it as the professional solution and it truly was. I tried just about every DAM system I could find, some where OK some were an absolute disaster (Fotostaion, I still get an icy chill thinking about that one).
Commiting to a DAM system is like deciding on the plans to build a new house and once that house is built, then deciding you want it made of brick and not logs is not very practical, even worse is when someone comes along and tells you we want you to change it to cheese, because we asked a thousand people what do you like best, bricks or Cheese.
Where will it stop? What happens if Apple decide pro res isn't worth the bother or raw handling is a waste of effort?
