Google will shortly be seen to be present on the
London Heathrow Airport. Passengers awaiting their flights will be able to check their mail and send instant messages here. Called Google Space, it will be used by Google to check people's response to its product offerings. Trained google staff will be present to help people.
This is part of google's effort to test the market for making its presence felt in transport locations like Airports and railway stations.
See BBC report on this.
