How many of you really feel like you currently benefit from the built in GPS? There are several apps that make use of it, but are they really that beneficial? One of the big selling points for me was the GPS as I was anticipating turn by turn software. I do think it is coming, but I'm not sure why it's taking so long. There are several other smartphones that have good GPS software. I am sure that Apple is capable of using a similar (or better) turn by turn solution.
