By the way, remember our "burning platform" conversation from a week before the Nokia/MS announcement was made? I predicted Android. Now, it looks like it finally came to pass!


Though my N9 is still my favorite phone ever, though I no longer use it (bad battery).

You wouldn't. Keep it in GL.

For anything related to video, assume that you will never get access to the 
actual pixels, either because of DRM or because it would just be too slow for 
the CPU. Any and every transformation that you need to do with the video must 
be done with OpenGL, directly on the GPU.
