I've been a fan of Google Maps for a while. The latest views are almost freaky in their detail ... I mean, to see my car parked outside my house is fantastic ... if not a little freaky. It certainly brings up the possibility of one's privacy being invaded.
When I searched for directions to get from home to work, the suggested route was a bit odd. It took me out of the fastest and most direct way, through a busy shopping centre, backstreets and 60km zones, rather than on the main road and an 80km zone. I hadn't realised Google maps had this directions option - I usually use Whereis. An advantage of the Google maps directions is that you can actually see a photo of your destination - that could prove to be useful.
