This shows an application developed for T-Mobile. The company will use Surface in some of its US stores towards the end of the year.
A mobile phone with a domino tag (left) is placed on Surface's top and the relevant information for the handset is brought up.
The customer can then select from the different talk plans at the bottom and drag them onto the phone to get an idea of pricing and so on.
In this picture, the user is selecting ring tones to put onto the phone and dragging them to the phone.
