Personally, no, what's the point in arguing? If someone likes something fair does. If you believe yourself superior to someone who has something different then you, you are just being the idiot you claim the other party to be.
People will start to flame, so I'd like to ask kindly that if you must debate, keep it reasonable and sensible, nothing about so and so's mom doing so and so to a jar.
Oh and if you have nothing nice to say without giving a good and fair reason (while still being respectful) why, just click away and pretend you never saw a thing.
EDIT: *sigh* If your going to go on about the PC being superior when it comes to gaming, consider the price as well (Objection!).
EDIT (of the EDIT): I have a £500 PC (not trying to brag here, (if I did I'd mention the fact I also own 2 laptops and 3 PCs...NOW im bragging) back to the topic) and i hardly ever use it (also before you say "no games, lololol" I have quite a few, no more numbers, no more bragging...FOR NOW!). The PS3 is my shindig I guess, don't like the mouse and keyboard.
