@banjomatic: Thanks for the feedback. On the screencasts front, our current plan is to get you started with the base API concepts and a straightforward/minimal example. So we have this intro video, and a similar 4-part introduction (part 1, part2, part3, part 4). Building on that intro to the core API, there is an intro to the tiled model (more API coverage). Looks like you read my mind , and next I will be publishing a matrix multiplication walkthrough screencast, and I have a couple others in the plans. Stay tuned here on the channel9 C++ AMP feed.
Our feeling is that once you have watched all those, you should be perfectly comfortable to download and explore the more involved samples on your own (without a video/screencast accompaniment) – please pick your favorite from the C++ AMP samples list. BTW, every sample has a dedicated blog post describing it, so if you have questions around understanding a specific sample, please leave a comment on the specific blog post for the sample, or ask in the C++ AMP support forum. Thanks for watching!
