Your bullet blender and your 10-speed blender will be useful for the same things, except the bullet blender "should" do a better job whipping liquids (they usually come with a flat whipping blade). They tend to run hot though, so be careful you're not cooking the things you're whipping.
A full sized blender is good for chopping ice, and blending liquids. I don't own a full sized blender because every time I've owned one in the past I've never used it.
A food processor is good at chopping firm things into smaller pieces, grating large blocks of cheese, mixing some doughs, etc. I also use my food processor to grate frozen butter into flour for biscuits, to "sift" dry ingredients after measuring,
The bullet blender fits between these two devices. It's a small blender, and a small chopper/grater. It really shines at chopping fresh herbs, grinding coffee/hard spices, grating cheese, and small amounts of veggie/fruit chopping, etc. I use my bullet blender for making fresh pesto, grinding up small batches of peppercorns for red sauce, grinding hard spices to make my own "apple pie spice", whizzing sugar and fruit zest together to help break the zest up for frosting. I also use it to finely chop ice for granita (a Sicilian ice snack).
