There are wireless bridges you can buy from the store, but I'm thinking they are going to cost around $50 anyhow....[/QUOTE]
Right, but even if they cost the same, one only lets you use your 360 online and the other lets any device, or multiple devices. Fact is, Microsoft makes a fat profit on these incredibly overpriced adapters. The next xbox will be wireless standard so these will be useless at that time. But a wireless bridge you can still use for something else.
I almost fell for the DS dongle years ago, and though one of my xboxes isn't wireless, I just can't pay money for such a product when there are cheaper and better alternatives on the market.
