According to http://www.forbes.com/sites/greatspeculations/2014/10/27/microsoft-earnings-hardware-sales-and-cloud-services-boosts-revenues/ http://www.forbes.com/sites/greatspeculations/2014/10/27/mic..., they sold $908 million in Surfaces, out of 2.45 billion total hardware sales (including Xbox), last quarter. Total revenue last quarter for Microsoft was 23.20 billion.
