Macrumors: A place where you can count on people proudly displaying their ignorance and spouting their opinions whether they know anything about what they are talking about or not.
First, this wasn't Phil giving a grammar lesson or asking anyone to do anything. Two of his friends were having a discussion about the right way to pluralize Apple products and Phil in passing simply said, you don't HAVE TO pluralize if you don't want. I wonder how people would feel about it if your tweets were scrutinized to this degree and used to determine if you were doing your job.
Secondly, he wasn't making statements at all about pluralization in general, just that PRODUCT NAMES are different than other parts of speech. Steve Jobs was always careful to not pluralize "iPhone" in keynotes and people here act like he's a demigod while Phil doing the same thing makes him an idiot.
Third, since Phil said you don't have to pluralize names, he is not being hypocritical when he does so, because he never said you shouldn't. Sometimes I am embarrassed to be a MR poster.
