What would I do without this thing. These littel gadgets are around $100 in most stores. I got this little baby, brand new, for $40 (still in package) when Circuit City was going out of business. Now that I have it, I can't imagine 360 life without it. Its much more convenient than have to run cables to relocated your router or tv to accomodate. Just go wireless. If you game alot, its worth it.
With this little bad boy, you can wirelessly stream music, movies and photos straight from another computer in your house or even an external hard drive. For example, I have all of my music, movies and photos on my external 500GB hard drive... I can access that 500GB hard drive from my 360 and watch movies and hear music straight from there (without the loss of disk space on my 360). It streams it all (all because of this adapter).
You can do this with a wired connection too... its just much easier when wireless. Plus, if your internet goes out or you can't afford it anymore... you can still pick up other signals from local homes and still play online. Awesome!
