We all said: Wireless is useless.
People who wants it, they just go buy the add-on.
The majority just don't care about wireless.
Hell, even my PS3 is connected with Ethernet Cable.
Even if I have a wireless router.
My experience: Much better transfer speed with cable.
As for Xbox Live fees, I'm very proud to contribute to such an amazing online service.
5$/Month is nothing.
Cheaper than your cellphone fees
Cheaper than a McDo meal.
Cheaper than the monthly electricity fees required to power your console.
