As for Bobo's questions, I don't see them as being argumentative at all. They're all valid questions and if you're planning on spending the money to buy the product, why is it unreasonable to want to know everything you can about it? He's asking questions that only somebody that's spent that money already would know to ask, so he could be saving you a couple bucks of your own depending on how his questions are answered...
