Hi just bought PS3 350gb. I am waiting for HD TV/Monitor to be delivered. I have a question. I understand that the PS3 can be connected to my wifi. However, I am not sure why you would want to have wifi. I would imagine that once connected to wifi, you would need a keyboard and mouse. Likewise I would assume you can surf the net. Is that correct? If so, does the PS3 have a built in wifi card? Or do you need to buy an external adaptor? Might sound a bit daft, but never having had to set a PS3 up before, I am not sure. Any useful help and information would be greatly appreciated.
