I like how your handle reminds me of "forest for the trees" as it's pretty appropriate ;)
Really though, disappointed? These are prototypes for the next generation of interaction, most people aren't even close to doing just one of the 5 ground breaking ideas he presented, and you expect him to release fully baked products?
Ha. I don't expect fully baked products but the prototypes feel a little avant-garde. Cool to look at but not actually useful or practical. Given the amount of attention it's gotten I walked away disappointed.

Show people the flash and the substance will follow. As I've said previously, if seeing that demo pushes me to try and implement it because it's painful to code after having seen it; then theres certainly many able individuals working on it right now. (I am a novice programmer in most respects, I couldn't do it. But damn if I didn't try.)
EDIT: Push does not mean I actually tried. But I'm getting there. Every time I sit down to code it nags at me that I can't see the code the way I always wish I could see it when I'm debugging.
