I purchased the wireless adapter when I first got my 360 and it̢̢̮ââ¬Å¡Ã¬Ã¢ââ¬Å¾Ã¢s worth the money. I did find that if I̢̢̮ââ¬Å¡Ã¬Ã¢ââ¬Å¾Ã¢m playing an old Xbox game it might lag now and then, or if you̢̢̮ââ¬Å¡Ã¬Ã¢ââ¬Å¾Ã¢re playing with someone who has a bad connection I would lag as well. I guess if you don̢̢̮ââ¬Å¡Ã¬Ã¢ââ¬Å¾Ã¢t want to run a cable go with the adapter. If you have the 100$ go buy it.
