Or, as I like to call it, the worst bathroom hand drying thingie ever invented.

The instructions on it say to move your hands up and down. Aside from making the user feel slightly ridiculous, this has another effect.

The blue arrows denote the direction of the airstream. Unlike conventional hand dryers, this one blows from two directions at once. And according to the website, they move at 400 MPH.
Combine this with the up and down motion, and you have an extra-fast dryer that is nearly impossible to use without having your hands being blown into one side or another.
In other words, Dyson has taken a device whose chief virtue is that it requires no hand contact with any surface, and made it so users will involuntarily be forced to touch surfaces.
Stick to vacuums and fans, Sir James.
