Bottom line, if you have a device with component outputs you don't likely need the HDFury. An exception would be if said playback device limited the resolution output from its component connections.
All BluRay players will limit the resolution over component if a disc is put in with the ICT on. Supporting ICT is part of the AACS DRM that players must support. Thus far, noone has turned ICT on, but they could down the road.
Also, as Trevor mentioned, the key the HDFury2 uses could be revoked, rendering it useless. This can be revoked with newer movies, so popping in a new disc one day may result in the inability to playback.
