A trendy device, often
popular for no other reason than being
popular. Some fadgets
may be original innovations, while others may be quite unoriginal, but enjoy success through clever marketing and manipulation of the mass media.
Derived from "fad" and "gadget".
If you're smart
enough to be wondering whether or not to buy an
iPhone, you're smart enough not to; nor any other overpriced, underperforming
Apple fadget.
