I have a tiny one I rarely use. It’s not technically collecting dust, though, since it’s in a closed cabinet.
If by tiny you mean a one-to-two cup clear bowl with a button you have to hold down to operate, then I can say the same thing. Except I am starting to use it because homemade humus is awesome. (Every already made version seems to use too much garlic. I know, that sounds like a foreign concept, but apparently it is possible. It tastes sour.)
I don’t use mine very often now, a couple times for crushing home grown dried peppers into flakes, and once for mushing up pumpkin, but I just got a Bullet from my mom that I forsee using a lot next year for baby food!
The tiny one I’ve got will likely go to Goodwill as it only chops pretty coarsely and you have to stop every 30 seconds and push the food back down into the blades.
Pie crust, quick ganache (heat up cream and a little butter, meanwhile throw chocolate into food processor and chop. Pour warm cream into food processor with blades running, voila, delicious chocolate sauce), dense whipped cream for filling cakes, pesto, salsa, cookie crusts for cheesecakes, roasted red pepper puree for pasta sauces, pumpkin soup, various home-made marinades, big batches of salad dressing, quick mayo with whatever seasonings I want for the dish…
A good food processor can have lots of uses 
Although I just got an immersion blender for Christmas so I expect my food processor usage to go down a little this year.

and many, many more which escape me right now
Huh. I have two: a little mini one and a second small one that was part of a blender/food processor combo. I barely use either. I do use them for hummus, and busted it out to make a rosemary/garlic paste with olive oil for the Christmas prime rib roast, but otherwise I never use them.
Perhaps if I had the larger version, a proper food processor, I might use it more, but I kind of doubt it.
I had one until about two days ago. The one I had was one that came with my Oster stick blender. I tried use it to make breadcrumbs out of some dry, crusty bread and it stripped the little plastic thing that attaches it to the stick blender out right away. Makes it pretty useless after that. I do have a hand-crank one, but that didn’t do much better on the bread.
I have three! I had my mini-Cuisinart for years, then acquired a second one when I acquired my second husband, who also had a Hamilton-Beach full size processor. One mini is stored away for whatever the future may hold, and I use the other two fairly frequently. The H-B model is big but it doesn’t do nearly as good a job. I used it for big batches of hummus, since I don’t mind some chunks in there, and for making pizza sauce, since pureeing tomatoes is easy for any processor.
If you have any desire to make cole slaw, though, you must have a processor. It’s just work without one, and with it you’ve got shredded cabbage almost before you start.
I used to use it to shred cheese all the time, until I got lazy (and the kids grew and we started using it more) and now I just buy shredded.
We have three. The little one gets used daily for things like garlic mincing. It is kept on the kitchen counter, is easy to use and clean.
Mid sized processor is used probably twice a week for salsas, sauces, humus type dishes. It is kept under the counter in a cabinet and is more work to clean then the small one.
The behemoth is kept in the basement on a shelf. It can do all kinds of things. You can practically drop in a cow and make hamburger. It gets used a few times a month.
I’ve got big, medium, and small food processors, plus a blender and an immersion blender, and they all get used. Though I’ve decent knife skills, when doing a large stew or pot roast, this is the quickest way to break down the vegetables. The Mini minces large amounts of garlic much faster than a press. Also good for pizza dough, chopping hamburger meat, and grating large quantities of cheese (hint - freeze soft cheeses for 30-45 minutes before grating).
Does anyone have any safe-saving storage tips for these? I got a huge one for Christmas with approximately 20 pieces, and the instructions ensure me if I store the bowl/blades/etc. on the base, I will die. But they are all pretty weird shaped. Maybe just throw them in their own tupperware?
At the risk of being repetitive, my large food processor gets used only when I make marinara sauce (I make about 5 gallons every few months and freeze it.) It is a bit of a pain to drag it out unless you are cooking mondo food.
I got myself an early Christmas present this year: after checking with consumer reports I bought the 4 cup Cuisinart chopper; which I LOVE!. I made fresh pasta with it and it worked perfectly. It takes up a tiny amount of cabinet space, does a great job, and is easy to clean. I would NEVER put any F/P parts in the dishwasher. The only other assisted chopping gadget in my kitchen is a stick (immersion) blender. Also a Cuisinart and a real workhorse for soups, sauces.
If I had to do it over, I wouldn’t have bought the full-size processor. OTOH, I’ve had it for 25 years so it doesn’t owe me a thing.
Mine gets used for mincing garlic and onion… and that’s about it. That being said, I use it for such purposes FREQUENTLY, so I’m glad to have it.
I don’t use mine terribly often. It just generally seems easier to chop things up by hand.
So yes, it has dust on it.
The main use for mine has been for making macaroons around Christmastime. Apart from that, it gathers a lot of dust.

Same here. A Cuisinart SmartStick that has this small bowl that works just great for recipes for one or two. The regular food processor is so huge and such a pain to clean that I gave mine away. I’d rather run multiple sets of ingredients through the small thing than once through the big, hard to clean thing.
