Yeah, I know what it does, I use 2 Linksys equivelent ones on my network. But why the comment on the M$ site "Play games on any TV in your home ". You don't need this box to play Xbox games on any TV in your house. Surely they should have said to play Xbox Live games on any TV in the house or something similar. i.e. make the point about live. It's very misleading.
