When Apple launched their Mac App Store recently, they put Aperture 3 in it and dropped the price for App Store purchase from $200 to $79.99. That’s a compelling price. After reading a few reviews and talking to my photographer friend, I bought it.
I’ve only played around with a bit to date, testing reference file rename/delete/move handling and such, I haven’t really used it for reviewing and cleaning up photos. So far it’s not bad.
