Dyson AirBlade: introduced in 2006
Mitsubishi Jet Towel: introduced in 1993
As soon as I saw the first AirBlade I recognised it. If the deafening over-priced recycling-centre-infesting vacuum cleaners hadn't already convinced me to swerve this shyster's products, the AirBlade finished him. Oh, and remember the contra-rotating drum washing machine?
Here's a thought. Build something simple and effective at a sensible price, and they will come.
