Central US here: I have one that I bought 35 years ago to heat water for doing dishes in the camper. It went into storage after we bought a camper with a better water heater.
Then we had our flood last April and no hot water in the basement for a while, so that little guy really got a lot of use heating water for cleaning.
It still works well, but if I were going to need a kettle, I would get a stovetop one. When we had a gas stove, water got to boiling nearly instantly anyway, and now I have a ceramic top electric stove which does just as well. I don't want to waste the counter space, anyway. I also didn't like the lime buildup it got - it would put flakes of lime in the water no matter now much vinegar I cleaned it with so if I did use it for food, I would use a strainer.
I don't know anyone else who has one, but several of my friends do keep a teakettle on the stove.
I had a hot pot in college - the only cooking appliance we were allowed in our dorms, and that thing really got a workout heating water for hot chocolate, which we could pick up for free in the cafeteria.
