Another kit's coming down the pipe to allow you to back up your files from your Xbox 360 hard drive, say, before sending the unit in for repair. The kit comes with a Optical Disc Drive Adapter, Xeno SATA HD Connection, and SATA-SATA cable. This allows you to "Effortlessly transfer files from your 360 hard drive to your PC without opening up the case! "
Not sure what the price is going to be yet, as the site says "wholesale only" for now. But using this to back up saved games or paid content may be worth the price of admission.
