The only thing that would make it worthwhile for me is the fact that you can't load any of the revised Adobe RAW converters inot CS3. This means that if you buy one of the latest DSLR's from any manufacturer, you will not be able to download or edit your RAW images in CS3 - you must buy CS4 to be able to use the latest Adobe RAW converter which contains the program codes for the newer models such as the D3x etc. Bit of a con job by adobe.
