I group people who will buy the Apple Watch into the same category as users of vaporizer/e-cigarettes.
The Apple Watch is the modern day equivalent of the Ford Edsel.
"The Edsel was an automobile marque that was planned, developed, and manufactured by the Ford Motor Company during the 1958, 1959, and 1960 model years. With the Edsel, Ford had expected to make significant inroads into the market share of both General Motors and Chrysler and close the gap between itself and GM in the domestic American automotive market. But contrary to Ford's internal plans and projections, the Edsel never gained popularity with contemporary American car buyers and sold poorly. The Ford Motor Company lost millions of dollars on the Edsel's development, manufacturing and marketing. The very word "Edsel" became a popular symbol for failure"
The only difference this time? The Apple Watch is going to cost Apple investors billions in market cap.
