DW and I had a dishwasher in our first apartment, which we never used (except as a drying rack). I didn't own enough dishes to fill it up, so it never seemed worth it. We bought a house in 2011, and it had an original 1960's kitchen, so no dishwasher. We moved in 2020 into a house built in 1994, and the previous owners had a bunch of fancy stainless steel appliances that are ~5 years old, including a dishwasher (Whirlpool Gold Series). When they die, I'll replace them with simpler (less computerized) ones, but for now they're fine.
We use the dishwasher regularly. As a family of three, we typically run it every two days. We use some sort of tablet thing, with no extra "rinse" or whatever additives. We do the normal cycle with no heat dry. It takes 2:30, and doesn't seem particularly hard on either our water bill or our electric bill. If it breaks, I *think* we'd replace it, but with something cheaper. Once our daughter is out of the house, though, I wouldn't be surprised if we stopped using it. I feel like, with two adults, it takes a long time to fill up a dishwasher. Plus, I'm very much in the "give something a quick rinse after I use it and stick it in the drying rack" camp. With children, though, it's nice. I also think I'm more pro-dishwasher because I work from home -- I can run it and unload it during the day when I want a short break. If it was yet another thing to cram into a weekday evening, I might like it less.
