I just got aperture over the holidays and love it. I imported my iphoto library as a managed copy so I think that the two libraries are separate from now on. The new iphoto '09 faces feature seems very useful actually and now I think I want to use it but I want to retain the image editing options of aperture. Any suggestions on how to use each program together. The only thing I think I could do is delete my aperture library, install iphoto '09, then re-import my iphoto library as referenced masters. Seems like a pain. Suggestions?
