I spent ten minutes with mine and threw it in the trash. Edit: But I'm not disappointed. First, I expect a certain failure rate with venture funding. Second, it was worth it to me just to see if they could pull it off. If I got a working keyboard overlay out of it, that would just be a bonus. Finally, I didn't expect they'd pull it off, because it's a really hard problem (which is why Apple doesn't have a solution for this).
