I intend to use Aperture to edit all of my pics, it has many advantages over iPhoto. But is it better to keep the pics stored in iPhoto and reference them back to Aperture, or stored in the Aperture library and then let iPhoto "see" them from there? I want to be able to use Front Row slideshows and have videos in my albums, hence the desire to keep some functionality of iPhoto. However I need to save space on the Hard-drive, if either option would make a difference there? Also I want the best organisational structure as well. What's the concensus? Anybody else do anything similar?
