The thing that struck me was the delay as the presenter waited for the preview to show. If that is a bandwidth problem, it looks like high speed internet just found it’s killer app. If it is a response latency problem, then Microsoft needs to keep building datacenters or the CDN’s just got a big bump. I am willing to bet that the purchase rate is directly proportional to the response rate.
Sorry for being so breathless but I think his is really a big deal. Who gives a hoot about stupid pet tricks on YouTube. People want quality content, and it looks like the content providers just found a premium distributor.
