(This is only if you're in need or want of a keyboard for your computer.)
-A 360 (duh)
-A usb keyboard
Step 2: To make it easier..
I'm sure any USB keyboard would work, but I prefer to use my Microsoft Wireless Laser Keyboard. Not only am I keeping well clear of skrewups between Microsoft hardware and another peice of hardware, it's also wireless. (Who wants all those cables cluttering up their living space?) It costs around $35.99
Step 3: The simplicity is wonderful!
Justplug it in and use it like you always do! Don't forget to connect it if it is wireless and you will be chatting on your 360, non-stop. The windows button brings you to media center.
