I am using graphic products for following purposes: Create images for web and for pre press. For the first purpose I need jpg and gif. For the second CYMK formats like tiff, jpg or pdf are needed. From my microsoft history I have hundreds of MIX files from photodraw.
From my point of view, Expression Design can do nothing better than other tools today
My essential format MIX not supported. CMYK support seems to be not implemented correct.
btw: i like the UI.
