On the software side, the BBC has partnered with Microsoft to develop a web based, drag and drop interface for programming called TouchDevelop. Samsung is also involved in the project as they are developing the Android app, and an iOS app is also planned.

The BBC will send 1 million pieces of the board to schools in the UK this autumn, but they also plan to sell the board to the general public, although pricing and availability information is not available yet.
