My wife's car has frameless windows, so we have a more fundamental issue on particularly cold days. Because of the frost, the windows fail to do their half-inch roll down, so firstly it's a hell of an effort to open the door - and then when you have, you can't close it properly again because the window won't go back under the top seal.
Hence the warm water or the heater in the car options are extra valuable for us.
