this is one of those applications which smart phones should come standard with. it's one of the applications that have made me stick with android. it's a very comprehensive map which has an integrated navigation software which is what i use a lot. one could buy a naviation device for hundreds plus pay for map updates, with this, you can just have the phone and your updates are free and it does what it's supposed to. just last week actually i had to use my google maps on my phone just to correct my friend's navigator device because we couldn't find exactly where to go with it. google maps got us there and could have gotten us there faster. if you travel a lot or a little but go to places that you don't usually go to, this is something you need to have on your phone.
