No video camera and laser pointer?
To give you an idea of the sort of use you could put such a thing to if it could run applications, a friend had some free airplane tickets and dragged me off to Utah a couple of years ago where they had a late season on cow elks, and we actually saw some cow elks, but the closest we ever got was about 550 yards at about a 12 degree down angle with about a 10 mph crosswind. Obviously, since nobody on the East coast practices anything like that or even remotely like that, we simply chalked that trip up to experience.
Now, there actually are exterior ballistics programs for PDAs, and if we'd had THAT with us, we could have taken the 550 yard downangle shot in the crosswind, and probably made it.
