Came across this looking at the gift issue of Consumer Reports. You can see their website at http://www.flypentop.com/. It's the most heavily produced, "Hollywood"-type website I've seen for some time. Quite impressive.

The technology itself is really intriguing. I suspect a lot of it is smoke and mirrors (e.g. you can't randomly adhoc, but instead have a fairly constrained set of actions, each with a limited set of options, that they just happen to demo, acting as if it magically correlated with their need), however it's an interesting approach - could this be an alternative to PDAs? There are a tremendous number of possibilities with that sort of technology. Interesting stuff.
