In the coming weeks, selected universities will be given a phone box which is connected to the Google Voice service which will allow students to call friends and family across the United States as well as abroad.
For me, the video does not provide me with the personal incentive to use it. While the allure of being able to call your friends or family from your inbox may be appealing to some, at the moment it offers the problem of being fixed to a desk like a landline.
Though you can take your 'phone' with you to other computers, you will find as many students ring home to speak to their parents, it is the student phoning from a mobile device and the parent receiving from a fixed landline.
In my opinion, they have the two mixed up. Unless Google Voice can be truly catered to a students needs, then it will not be as popular as the far-more used Skype. The London phone box may well be a perfect metaphor for the problem Google clearly faces.
I do like the red telephone box though, but maybe that's because I have one at the end of my road.
