This talk has three notable things:
1. David Pogue, tech writer and nerd for the NYT. I don't normally like him, so take that into account when I tell you that you need to see this.
2. It looks like a big email forward - and it is delivered in the same frenetic manner.
3. It is right. Look at how hard it is to make an interface easy - and look at how much people are willing to pay for it.
