The title asks it. I would use if for mixing in saucepans, or possibly making smoothies (says the person who has never made a smoothie in her life!) or doing other light mixing chores. I actually picked up a Bamix at William Sonoma, and found it to be quite heavy, and also expensive. I'm pretty strong for an old lady, but that seemed too heavy to hold for a long time.
I could use one of these, but I don't know whether my price range is realistic for an immersion blender that works well and would give good service.
