I am like others... At home I use my oven frequently. I would expect that as a feature of any home I would buy, to live in.On vacation I rarely use an oven. Occasionally I stay someplace with one, and use it, but I wouldn't not stay in a rental because it was missing an oven. I do agree I would expect the cooking room of such a rental to be labeled a "kitchenette". Even if it had the best toaster oven on the planet on the counter.I would tend to agree, at least to the extent that presently available portable ovens leave some things to be desired. On a day-to-day basis, I find a conventional oven a nice convenience. I certainly could get by w/o one, and do a very respectable job, but really don't care to.WRT "How Necessary is That Conventional Oven", I submit that it is certainly very possible and plausible to prepare very excellent baked meals w/o one.
