I do love my food processer- We are on our second one. We buy whole blocks of mozzella cheese and shred them and freeze. So its ready whenever we need it. Also it does a great job on chopping!
I hand do my pizza dough unless we plan on grilled pizzas since the processor makes a tougher dough which is needed to grill pizzas.
I got a bread machine for my 21st birthday (many many years ago!) and went thru 2 of those as well. The second one sat in the pantry until my declutter and someone who works for dh wanted it. I just love hand kneading my own bread so no need for that gadget.
As far as the microwave- its not for cooking! Its for reheating etc. We used to only cook popcorn but now we do it right on the stove. It tastes so much better and I use organic corns.
We also never installed the ice maker. We have ice cube trays that work just fine. We have 3 stacked in the freezer and when one is empty, we put water in and stick it at the bottom.
Then only big time gadget is our coffee bean grinder. Its a very expensive gadget that we use every morning. Also our maker/pot was a hefty price but it should last 20 years or so. We also roast our own coffee so we are a bit of snobs for coffee- fair trade/organic blah blah blah. We have coffee every morning and iced lattes (soy for me) at least 4 times a week in the afternoons. If we went to a starbucks or something for our habit we estimate it would be about $1000 annually. But now its a little under $200 a year in the end.
