plastique2: Lightroom does not do the same job - at least not on Windows. ACDSee's database management properties are better, more simple and faster than Lightroom's, Aperture's or iPhoto's. I have tried ACDSee on my Mac, it's very slow and by far not as good as the Windows version. Hopefully the new version is better, although some of you say it isn't.I have installed Windows on my iMac because I haven't found any solution for the OSX environment for a fast image processing workflow as is the combination of Adobe Photoshop (Elements), ACDSee Pro and FastStone ImageViewer. All software solutions I have tried on OSX are a joke mildly spoken.Of course - if I had the apple virus in me that makes me love everything apple no matter what - then I'd still be fumbling in Apple's Preview and always preselect the images I want to view in a row and imagine how good that I have to do this this way - there must be a higher reason for this which I haven't figured out, but Apple knows for sure, so why worry.
Xee is a fast image viewer on Mac.
