I TOTALLY agree... the GPS craze right now it just that.. more of a fad.. all of the GPS nav things you see in cars... great idea, but how often are you really lost or do you need to get directions some place? I would bet generally they just sit on the dashes of cars sucking power from your battery.
Now, having said that, I DO use google maps a great deal in my work: finding out where a client lives, getting directions from where I am to someplace else.. and probably most of all, NOT USING 411 anymore!!!! Gdamn that costs a lost of money, great to be able to search for a business and have the phone number right there.
I find this post humorous. You start off stating you don't use GPS much, and therefore you wouldn't find such a feature useful on the iPhone. Then you go onto say how you "use google maps a great deal in my work." Have you considered the reason you don't use GPS is because it isn't convenient and that if you had GPS on the iPhone you would end up using it a lot?
You are right, most people won't even use GPS weekly. However I'm going to new places often enough that I would find such a feature very useful, I'm doubt I'm alone when it comes to this.
