Whorf on Language

The Whorfian hypothesis (Also called linguistic relativity) came up a number of times as we started to think of product descriptions in many languages.  Are translations equivalent?  How much so?   I recall reading many very different opinions about it's relevancy.  Here a review of a book:   Through the language glass - Why the world looks different in other languages by Guy Deutscher that touches on the subject, in particular how verbal descriptions can change memories of an event, or visual impressions.  Have not read this as yet. With implications in marketing too.
