The Dyson is just one model of the modern jet/turbo type hand dryers. The first (LONG before Dyson) was the Mitsubishi Jet Towel. Others include the Excel XLERATOR, American Dryer Extreme Air, World Dryer SLIMdri/SMARTdry/Airforce, BluStorm, Saniflow, ASI turbo, and more.
Personally, I HATE them all... The noise level is ridiculously ear-shattering, and even in low-traffic restrooms they leave wet trails across the wall and a puddle on the floor underneath them. Even at 3X the operating cost, I'd gladly go with warm air units.
