More seriously, consider how you are allocating your resources. Presumably, there is a limit to how much money any of us can plow into outdoor/survival gadgets. Would you be better off with the survival tablet which gives you comms and an emap or a well rounded set of more trad survival stuff, like firestarters, FAKs knives, and warm clothing?
Although, realistically, the planned retail on this isn't that much more than a decent GPS (and a bit less than some of the higher end units). So, cost wise, I think this is comparable enough to a GPS that the added feature-set might make it worthwhile for those looking to make a purchase in this area. For those with the gear already, it may not be something that would provide good value for the money, but it may be worth keeping an eye on for the future.
Again, I'm thinking it is fair to liken this to the type of device convergence we've seen with smartphones and I won't be too surprised if this concept becomes the future for backcountry electronics.
