That it is at light speed is not the point, radio waves also travel at light speed, the point is that lasers are able to carry more information than radio waves.
The data was scrambled and full of errors and very slow delivery so it doesn't seem at all practical to do this through the atmosphere but I think it would be invaluable for data transfer between two space-borne platforms. Massive amounts of data could be transferred error free without the interfering atmosphere to impede the beam. I think that in the not to distant future light will be used throughout most electronics including microprocessors.
