I migrated out of Aperture but maybe I shouldn't have panicked. A good friend is using it, and very efficiently right now. The new PacPhun apps come with plug-ins for Aperture (along with Photoshop, etc) that add almost anything aperture lacks. That and the always fantastic file handling and creation of an attached second file when using a plug-in, etc. really works. She's delaying her migration indefinitely at present, waiting to see what the Fall's system update has in store for her. Her patience is paying off for now.
The Panasonic LUMIX S1H has just received a firmware update to version 1.1, adding Profoto support (as seen on S1 and S1R) and addressing a VFR bug.
