Steve Ballmer, to the WSJ about Windows Phone 7:
In a sense, you could say we missed a cycle. We had some execution issues from an R&D perspective. In the time frame since the last significant release certainly the industry has moved, the technology has moved, the hardware has moved.
We said, we’ve got to move forward, not shoot for yesterday. We’ve got to shoot ahead in a way that’s delightful to users, accessible to developers and prioritize everything else we do around those elements.
