imho 5.5 is one of the best versions of Photoshop ever, so i can see why you've stayed with it for so long. I have CS3 at work and i like it One feature I cannot live without is the Screen Mode, that lets you position a corner of your image in the center of your screen to work on just that area. Layer Groups is a very nice feature which lets you select a few layers and cause them to group into a layer folder, which you can then turn off the whole set or move them all at once I use those 2 features most every day
