"Strikes me that Google are being left behind somewhat."
Google maps on my iPad is far better than the new Apple offering. I was in Provence in June/July of this year, and used my iPad to navigate from the airport to the remote farmhouse where I had to meet some people. I was amazed to find that not only did Google maps deliver me right to the front gate, but that it had a street view image of the farmhouse.
The new Apple application can't touch Google maps for detail and accuracy- at least not yet.
