I hope that this thread is not considered off topic for this site. I realize that electronic music stands are not your standard e-book, but musicians need to read too.
I think that the stand in the video is a MusicPad Pro by Freehand Systems.

Sadly, the MusicPad has had less than a stellar reception from the musical community. Its proprietary format for scores, and small amount of internal memory have held this unit back. Its original price, which was more than $1,000 USD also hurt its sales.
