Correct, the Xbox 360 doesn't have built-in WiFi, requires a separate WiFi network adapter (Amazon.com Link)
The 360 has 3 USB ports, one of which the WiFi adapter will take up should you get one.
So that bumps the price up close to a PS3 if I get that. I don't want to run a cable across the room to hook it up so I would need WiFi.
