Well the reason they convince everyone that it's going to be big is because of how they repackage it. That has been the case from the iPod on and again here with HDMI. As others have mentioned, I don't need anything more than just my iPad for HDMI presentations now.
And I'm sure it will be... Just makes me feel like I'm going crazy though (as I type this on a laptop connected to a 24" HD monitor via HDMI).
