I've wanted an immersion blender for a long time, but when I saw this one I had to get it for myself.  The immersion blender is great, perfect for making salsa and I've learned how to make some great smoothies for the kids also.  Great for mixing pancake batter or just smoothing out tomato sauce for canning, there are a ton of uses.  
All of that and I haven't even got to the other attachments.  The whisk is ultra-powerful, you have a great GE motor moving around the little lightweight whisk and it makes for quick work beating eggs or whipping cream.  The chopper/blender attachment is great for preparing vegetables for cooking and has replaced the dedicated appliance I had just for that purpose.  
This is a great blender on its own, but the attachments really put it over the top, highly recommended.
