So excuse the geek moment but many many years ago, probably when I was about 10 years old, I saw a picture of a fighter cockpit with a moving map display. Back then it was quite literally a roll of paper that scrolled around and it was inertial since the concept of GPS hadn't even been thought about, but I remember being totally awe struck on how cool that was. Imagine if one day that could be in cars. I've kept the picture ever since, and I've shared it here for fun. For me, turning the page in my "How it Works" encyclopedia and seeing that image was the defining moment in my subsequent love affair with GPS.
Anyway, fast forward a little. The iPhone. I turned mine on the other morning and went for a walk. At the end of the walk it told me that I had done 5.01 miles burned xyz calories, gave me the complete Death Star technical read-out and gave me the picture below with map, elevation, pace etc (correct to within about 20 feet). What changes we've seen.
Anyway, if the walk happens today, perhaps I'll log it and share. Should be a good souvenir.
