I use it and I love it, the RAW tools are great and the export options are pretty good too. Apple does a "test-drive" of this software from time to time. I think they give you 30 days to use it and see what you think. I like it cus its easy to use, has a back-up feature for your master files and integrates with all the other Mac OS features & programs. I know Adobe Lightroom is very similar, they are both the same price too. Unless you buy the academic version of Aperture, then its only $150.
