chewitt, that is a fair statement in general for RPi users but Intel users can benefit much more.. LE is a good platform for hosting headless servers including PVR backends and the work of installing the backend is done for the user via packages (TVHeadend, VDR and NextPVR, anyway) and many users don't have to hunt for drivers or firmware.
There is also a class of users that simply want legal live tv, and for them a USB dongle, or even a remote SAT>IP or HDHR device will work ideally. It is certainly better to by a stable USB device, Geniatech is one of the worst vendors, even on standard Linux.
