In my house, it's microwave, hands down. This magical radiation oven can not only make pretty lame brownies, but thaws, softens butter, boil water and dehydrates nori in humid summer.
My house does not have regular menu and meal options are decided at the last moment and always in need of quick thawing or frozen chickens, steaming broccoli / dumplings, and cooking hotdogs. I suppose I could eliminate the use of the device only if I plan it ahead but it's so effective. Please do NOT cook bacon in microwaves. Bacon is not meant to be healthy. If you're worried about he bacon fat, you should stick to bacon bits, for I believe there is vegetarian version of it as well.
I don't really see the great use of food processor in my home, and I've got by with broken one cup processor for years. I really only use it to make bread crumbs.
I use kitchen aid stand mixer more than any of the listed. I used to use blenders to make home made dressing but the clean up was too much hassle now I use good old whisk.
I do not own a pressure cooker and I wish I did. My mom cooked rice in pressure cooker and them were good. I never found bread machine attractive. Kitchen scale comes in handy, although I think it's hard to call that an appliance. I suppose there are electric ones but there are also digital thermometer and timers as well which aren't considered to be appliances.
I wish I had ice cream maker, largely because I have never used one before. Then I don't have to substitute sorbets with granitas and semifreddos for ice creams.
We don't have too much deep fried food and I always have hard time using all the left over oil from frying. Pretty much only deep fried food we make is sweet and sour pork/chicken. I've learn to pan fry everything, so that we don't waste oil. I have pan fried, onion rings, fries and battered chicken, pork, fish, and beef. Why is it that I miss having the deep fryer from time to time?
