OVERALL GRADE: B
Amazon: B
I said Amazon would expand its touchscreen line, but I predicted both a larger tablet and a phone. No phone (yet).
Acquisitions: A
I said there would be lots of acquisitions in cloud and big data. Boy, were there. Oracle, Salesforce, IBM and Microsoft all paid up.
Android: A-
I said the Android ecosystem would suffer as Amazon-driven fragmentation intensifies. That's happening, but no crisis so far.
Windows 8: C
In my most controversial call, I said Windows 8 would be so polarizing that it would either wildly succeed or fail, resulting in a leadership shakeup and Bill Gates taking a more active role. It launched too late for a verdict, but the leadership shakeup already happened with Stephen Sinofksy out.
