The case of the Microsoft Surface is melted down in the manufacturing process and then moulded to the details needed for the design. Bevelled edges have been utilised in order to make the tablet comfortable to hold. The ARM-based version of the Surface is only 9.3mm thin.
The Surface utilises a magnetic connector to attach to a keyboard dock. There are two covers available. The first is a 3mm thin accessory called the "Touch cover" that uses a full multi touch keyboard and also includes a trackpad. The Touch cover is available in blue, red, pink and white colours. The red version is shown here.
