"In this author’s opinion, motherboard manufacturers would much better serve their customers by offering an HDCP enabled DVI output with a DVI-to-HDMI adapter, instead of HDMI outputs."
Wow. You seem to be REALLY missing the point here. The whole point of this is for HTCPs, and the nice thing about HDMI is that it can send both video and audio to your tv over the cable. If they had a DVI port on the motherboard and you had to use an HDMI adapter, you would have no sound. Doing it the other way around though ensures that people who use it for an HTCP like it is intended get their sound, and those who want to use a monitor buy a DVI adapter. You didn't even seem to mention or test the capabilities of sending audio over HDMI!
I don't complain about my laptop not having a DVI out, and when I want to hook it up to my friends 32" HDTV all I have to do is plug in a simple HDMI cable. If I wanted to run and LCD at home I'd buy an adapter.
