I don't agree with Gabe's conclusion that "post-touch, and we’ll be stable for a really long time" As you said: "where I'm looking", "where I'm gesturing", and "where I'm thinking" are all possible - but totally different. I think if post-touch gets critical mass, we'll see a much more diverse and dynamic space of interfaces. An implication is that which interfaces to support would be a much more important decision - right now you can just default to building a web app and a touch app.
