Over the last few years I've been doing the dad's taxi thing. Taking the kids to various friends' houses.
Being fairly clumsy fingered I just put the postcode into the device, not the full address.That identifies the street and can look for the house number myself. Yet even when going to a place I've never visited before the device will all too often identify the correct house for me, ("In 30 yards your destination is on the right") even sometimes showing me a picture.
Now that is very impressive, and I guess makes the task a tad easier.
But it's still very creepy. Call me a Luddite, but I do not like it one bit.
