http://arstechnica.com/reviews/apps/aperture.ars From the review: 'It is also disappointing to see form beat out function here, but hopefully this will be Apple's software equivalent of the G4 Cube. They have only themselves to blame: they set themselves up for a big fall by attempting to dig themselves a chunk of the pro market by purporting to have the lossless holy grail of imaging. The trouble with that is they obviously didn't have the engineering or expertise in RAW processing to pull it off or, if they did, they chose not to include it because of speed constraints due to Core Image.'" Disclaimer: 1. I have not used the program myself. I am looking forward to it though. 2. I'm not trying to start anything but this is the first actual review I have come across since the product has been released. 3. Don't flame me, I'm just the messenger.
