External Scalers like DVD0 Edge

I think a big market for the Edge will be those with early HDMI receivers that don't accept 1080p. There are many of us that have receivers that are 3-4 years old that only accept 1080i or 720p through their HDMI inputs. Many of us will be upgrading our displays from 720p to 1080p now that it is so affordable. The Edge is the only processor I know of that has an audio only HDMI output which makes this issue moot.

That certainly could be true, but it certainly is nice for those that have first generation HDMI receivers. Many of these do not allow 1080p input at all and the Edge provides a good workaround. Whether or not it's better to upgrade the receiver or add an Edge will be my choice.
