The PS3 is not expensive because it uses standard accessories that people are free to buy as they please.
I do hear your point, but I disagree with it. Of course the wifi on its own wouldn't cause a price reduction. I'm saying that a whole line of accessories and paid services together would have made the base price lower. Wifi is just an example of a lost revenue opportunity. To me, any console that has USB ports doesn't need a luxury item like wifi built inside the box; all such things can be add-ons; that is the point of USB. And no, I don't think Sony made these decisions just to be my best buddy. I think they blundered, and will not release this kind of console design again.
