[Whiplash Performance]

I use my Droid to do all of that.

I like using my cell phone as GPS since every now and then I go all over the country for my job, I don't have to remember it and not another thing to carry.

Also since I have a few cars I don't have to move everything from car to car to use gps. Since its a cell phone its small and compact. Since it's your cell phone you dont have to worry about somebody breaking into your car and stealing it, since you'll have it on you.

I've used my droid a few time to find walking directions to places I need to go in the city.

Since my Droid uses satellite instead of cell tower triangulation like many cell phones do, it never has an issue with finding my exact location.
