Is Xbox 360 "Wireless Ready"

I was just on the Xbox.com website looking for details about the Xbox 360 Quick Charge Kit and I saw the advertisement above.

Did you know the Xbox 360 is wireless ready? It all depends on what you consider wireless ready. When you see the word “wireless” nowadays do you think of wi-fi Internet access? That’s what I think of first, not necessarily the controllers or a headset.

Granted those are wireless accessories and they’re great items being wireless. But when I think of a console being “wireless ready” I’m thinking of Internet access. When I think of wireless ready Internet access I’m thinking Nintendo Wii now.

With the cost of the Xbox 360 wireless receiver sitting at $99 at most retail locations, I just don’t think that many people are really taking advantage of the wireless capabilities of the Xbox. I think they should pursue the printer/ink method, drop the price of the wireless receiver in half or less and expect to sell more Xbox Live memberships and ongoing Xbox Live purchases.

Have you already purchased the wireless receiver? If not, would you purchase one if it were half the price it is now?
