BTW, I think that the author (or Alan Adler) has the invention date of the AeroPress wrong. I copied the date 1994 from the article, but I think it should be 2004 of 2005. (And the Aerobie ring was invented around 1984.)
Otherwise the period between invention and mass production and sales is over a decade. I remembered that I ordered a box directly at Aerobie in the USA in 2006 because the AeroPress was not yet for sale in The Netherlands.
