The amount of money these companies must spend on giving free mapping apps amazes me. If Microsoft had been the only player, we'd be paying mega-bucks for it. But I'm frustrated with the navigation app on my Android phone. The round-about icon always shows the same icon, i.e. turning right, unlike a Tomtom where the icon shows the direction of exit. And the arrows on the motorways are only a few shades of blue different from the motorway it's self, sometimes making it really difficult to see. Plus having a GPS connection and Data connection at the same time really sucks the battery dry really fast (the phones get really HOT when running these apps).
