The FP is great for things like slicing, shredding, chopping, mincing, mixing or blending. I use mine to chop nuts, make bread crumbs, cut fat into the dry ingredients for pastry doughs (like a pastry cutter), grate cheese, onions, etc. (like a box grater); slice vegetables or meats thin (like a mandoline), etc.
The thing I do not like using it for is working with liquids - like making emulsions (like mayonaise) or purees (like soups). I use a blender or a stick blender ... much less chance of a mess. The center column of the bowl is shorter than the outside height of the bowl ... I have found that if you add liquid any higher than 2/3 - 3/4 up the center column it will be sucked up and leak all over the place. Of course, if you're making a meat puree, like for pate, that wouldn't be a problem.
