Anyhow, I just installed CS2 and already I am loving it. I like how instead of having to right click on the layer to duplicate it or go to blending options you can just click in the middle screen, very convenient. I think you can also imprint a watermark into your work. Haven't played around with that yet. THe blending options are very simular to what was in CS. There seems to be the concept of a "SmartObject" not quite sure what it does yet. Also there is a "red eye" tool, which I think wasn't in CS.
