In case you did not know, the Apple App Store is now available (need to update OSX first) and there are some great deals! The best of these, from what I have found so far, is Aperture for only 80$! While I am now a converted LightRoom user, I can tell you one thing: at this price point Aperture is a much better value for the budget conscious photographer.
Looking at the top paid app chart, it seems like I am not the only one thinking this!
