If you've been into Best Buy at any point in the last year or so, you've almost certainly done a double-take as you walked past a seemingly benign end-cap displaying two flashy window fans. Last year, Dyson (the company that introduced to the world the bag-less cyclone vacuum that never loses suction) came out with yet another elegant, innovative, and very expensive product for the market...the blade-less fan.When I say blade-less fan, that's literally what I mean (although Dyson has decided to name it something a bit more inventive - the "Dyson Air Multiplier.") The fan consists of a cylindrical pedestal with dial and button controls, on top of which is an over sized wedding band with nothing in the center. Essentially a donut on a stick, except the stick is really fat and the donut rather thin.
