BendDesk

I think the point of this is that it allows both types of interactions. Steve Jobs said that multi-touch is not great for laptops because people don't want to stretch their arms like that. One obvious solution, shown here, is to make the horizontal and vertical surfaces just one bendy surface, and thus allow people to switch back and forth between the two without thinking about it.

So for example, you'd have your keyboard on the bottom surface. You might drag a document there to tweak various bits of it, then when you're done tweaking you move it back to the vertical half to look at it and scroll through it. At the same time.

Seems very smart to me. Now they only need to spend the other 99% of the development time to get the thing to be usable, cheap, reliable, and so on.

I would love to have it as an option.

Large arm movements tend to cause considerably less RSI than mouse/keyboard. They are tiring when you start, but eventually you build up enough endurance, and you can do them all day.

Yes, exactly. This is a (real) implementation of the Starfire ideas. Not to detract from it, just an observation.
