I’m with Stuart here. A food processor is a great machine. We have the old Vita-mix.
Talk about ugly. @jeremy mentioned not knowing what the tamper is for. With these machines, at least the old ones, things could stick to the sides and then the blades would spin on nothing. So the tamper would be used to push things back down into the blades. Edit: You may notice there is a plastic sleeve on top of the dome. That prevents the tamper from going into the blades. Guess what happens when you (I) forget to put that sleeve in?
But, we find a food processor to be much more useful. Can you make mayonnaise in a blender, yes, but it’s much easier in a food processor. Same with almond butter and grating vegetables. These could be done in a vitamix, but not as well.
However, a blender would be more practical for drinks and other uses. Just need the proper tool for the job. But, I would give up the blender before giving up the food processor.
A powerful blender would fare better with an ipod than a food processor, even if it might upset our resident Apple fan-boy. (Ahem, Pharaoh @jonobacon )
Another edit: I do not like the Vitamix company. They figured out that the machines they made will never wear out. For a while they tried to tempt us with new machines by offering us money for the old one. But, since ours still worked fine, why should we fork out more money? So, they went on a different tack. These machines need gaskets, especially the dome gasket, for it wears out often. Their solution? Stop making gaskets for the older machines. Thankfully, I can make my own.
