The x360dock is a USB ISO Loader for the Microsoft Xbox 360 console priced between $72.95, to $90 USD. It allows you to play downloaded Xbox 360 ISOs from the internet on your Xbox 360 console, without having to install modified firmware on your disc drive. The x360dock is quite unique. It allows you to play ISOs directly off your computer's internal hard drive, by using a standard Mini USB cable. So no need to go out, and buy a external hard drive. Similar Xbox 360 USB ISO Loaders do not have this feature, and are priced a bit higher than the x360dock at the time of the writing of this review.
