Definately not a concern when backpacking.

In a single walled cup the idea is that you do not fill the cup all the way to the rim; in fact I only fill mine around 3/4 full and by the time I have placed my pot on the ground and extinguished my stove I am able to drink from the cup without burning my lips-- and stays warm throughout my breakfast or dinner, which is long enough for me.

True, if you want a mug to take to work, class or to use around the home then a doubled walled is probably the way to go in order to keep your beverage warm enough for such a purpose. In the back-country, one often doesn't mull over a cup of coffee for a hour or so and thus a double-walled mug is not much use.
