Many people make mistakes, but not as big as the one that Apple did. On Apple’s website the specks of the iPad 4 said .37mm thick instead of .37 inches. With such a big size error I don’t think that many customers would believe that the iPad 4 is that thin. Apple has corrected the error since it was noticed. For an example of the size that Apple had on their website for the iPad 4 (.37mm) a penny is 4 times the thickness of the “size of the iPad 4”. Maybe Apple will spell check next time.
