Pixelmator. For everyone who, like me, feels ripped off by Adobe because they simply pushed PSE 10 as a new product into the App Store instead of following the usual practices there and releasing it as an update for PSE 9 (not that I'm particularly surprised - Adobe has been pulling such stunts with the product for a while now, that there are no more free updates). I just want to point out Pixelmator again. Much cheaper, visually much better structured, much smaller (I find it ridiculous that a photo editor must occupy 2.6 GB on the disk without the possibility for the user to select what they really need). For me, the essential tool is the Healing Brush (since that is the retouching tool that Lightroom does not have in an adequate form), and Pixelmator also has it as a tool and delivers good results for me. PS and PSE are now history for me. Warning, Pixelmator appreciates a slightly more powerful CPU and a bit more memory - with large images, I notice short pauses on my MacBook Air 13" from time to time (not really critical, just noticeable).
