I am wondering if digital maps on screens can reach the same availability levels as a printed paper map. For such a system, is it more beneficial to the user to have up to date information most of the time but be at risk to have no information in rare situations. Or might it be better to be able to guarantee that some level of information is available to the user at all times.
