Don't know if it showed up in this thread but there's a few videos around of some -very- nice looking programs for the diamond/pro... Problem is they're fake, if you look closely, it's very likely just a video playing, as the movement of whatever was on screen, wasn't really responding to touch, you could pretty easily tell the person in the video was just faking it.

Which isn't a problem really, these guys are there to just come up with ideas, and they do have some excellent ones... unfortunately, most of them may never see reality.

Edit: This is one of the videos:
