Now this is an interesting concept - Skype phone booths. The project is underway - the first booth has been installed at Tallinn Airport in Estonia. Travellers can use the booths to place calls using Skype credit, in the same way it works at a home computer,
A 22-inch touch screen lets you see the person you are talking to, and there's a headset so not everyone else can hear.
So why Estonia, you might ask - well it seems Skype was born there. The company plans to extend the project to cover other airports, as well as hotels, hospitals, shopping centres and so on.
