Your post was riddled with half-truths and outright incorrect statements. But I will reply to only a couple.
First off, displayport is a VESA standard.
Next, check out the Dell e6400 notebook line. Displayport only.
Additionally, the four letters you didn't mention in your post, that seem to get ignored a lot in the HDMI to displayport comparisons: HDCP.
HDMI has it. Displayport does not.
Displayport supports HDCP (in version 1.1)
