There is a debate as old as matza machines about the kosher for Passover status of their products. Many people believe they are chometz while some believe they are less likely to be chometz than hand made ones. The reason being that there is less chance for human error when a perfectly engineered machine runs its course. Some people only use hand made during the Seder but use machine ones during the rest of holiday, while others specifically use machine matza at the Seder for the reasons stated above (ie students of Telz yeshiva.)
I have no opinion on the matter, other than being sure machine matzos are kosher and I use them.
The Forward posted a video today of the Manischewitz Matzo factory machine like you would see on the TV show 'How it's Made'. After watching this, machine matzos seem inauthentic, and sterile, and corporate. I'll still eat them, but the idea of fulfilling an ancient custom with something produced in this way just seems off-putting to me now.
