Regarding your confusion over the logo brands (which I shared in), I think some of the choices were made to distance Surface and Windows Phone from the Windows brand. This is why in this concept, Windows Phone is "surface phone", and it uses a simple slate icon rather than a double slate that would refer to the Windows brand. At least that's what I got out of it. Still a little confused. EDIT: I think this image might clear it up: http://www.minimallyminimal.com/storage/post-images/microsoft/m10.jpg?__SQUARESPACE_CACHEVERSION=1341179600868 http://www.minimallyminimal.com/storage/post-images/microsof... It appears that the single slate logo is Surface, the double slate logo is Windows, and the intersecting slates are Office.
