Similar to Glenn, I prefer a warm dinner. Sometimes if it's cold I'll heat water a bit for my breakfast drink (or oatmeal).
This summer I did my first no-cook trip (6 days mostly off trail) and it was a success. I did take my stove just in case and did use it one morning even though there wasn't a real need. It had gotten down to 18F and I didn't really want ice cold water for my breakfast drink. I could just have well hiked a while first.
Can't say how often I'll do that, but it was a good experiment.
