Yes, as far as I know. Adam will be able to speak more on this. > Ruediger, what is the effect on the install scripts? Minimal I would think. We still have to configure the device, it just configures differently. Ruediger is not proposing dropping support completely, just that we treat it as we would any other input device. I think this is a good idea overall, especially if it pushes more folks towards using a scaler.
