jm67: I hear you Danny. The main reason I've upgraded from version to version is for the raw converter. I was fairly happy with CS3 but of course it wouldn't support newer Canon cameras I had at the time and then I've gone to CS5 cause of the improved raw converter. I'm getting to the point that I'm going to be looking for another program to convert my raws and then stick with CS5 for further processing as the trend is likely to continue that if and when 5DIII, 7KII comes out it may or may not be supported by CS5 and I wouldn't be surprised if I'll need CS6.
You can always use Adobe's free DNG Converter http://www.adobe.com/products/photoshop/extend.displayTab2.html to convert the latest supported RAW to DNG and continue with your older version of Photoshop.
