I would agree completely. One measure of a windows performance is "how comfortable" the room feels.
Heat goes to cold. Nature likes balance. The colder the windows, the more uncomfortable it is to stand (or sit) close to them because they are drawinf heat from your body in an attempt to equalize temperature between you and the window. So increasing the temperature of the glass surface really does make you feel physically more comfortable.
