i am debating on purchasing AW 2 for the fact that it has GPS, but other than tracking your walk, run or hiking etc etc what other functions can it do?
GPS is just point measurements and any thing done is this info is App dependent. As of now only the Workout app uses the GPS data. Most announced Apps are fitness (running/biking) tracking related. A guided trail hiking App was shown at the event. Only time (pun) will tell what other types of Apps take advantage of the GPS data.
