GPS to me personally, completely useless, i will personally never need it, and even if i did have it, still wouldnt use it.
That seems very final. I remember thinking the same thing about this new "text messaging" a few years back. Why would I want to send a message when I could CALL someone faster? For that matter, why put a camera in a phone? I have absolutely no interest in that!
Look how things have changed.....
Most people think of GPS as a point to point navigation device. I have one in my car, so I don't plan on using the iPhone's smaller screen for navigation - especially if I will be using it as a phone while driving. The bigger picture is not navigation, but location services. Instead of Googling a Starbucks, you could Google for the closest Starbucks. Take a nice picture of Golden Gate bridge? Post it to Panoramio instantly the utilizing GPS meta data. The possibilities are endless, and who knows what kind of cool location based apps are coming.
In one year, will GPS be a "must have" like cameras or texting? My money says YES.
