The only thing that really concerns me about this system is the tabs on the pod that lock the pod to the coil/mod: I'm curious as to whether or not there's been any extensive testing of the longevity of those tabs, if they're reinforced in any way, and if the next model might consider some kind of strengthening of these tabs. This, it would seem, could possibly be the weak link in the system.
According to "The Hitchhiker's Guide To The Galaxy", when in doubt, the answer is ALWAYS 42: therefore, the answer to the equation in the first picture is 42!
