Since we're talking so much about HDMI inputs, this article may make for an interesting read. Basically, custom installers and folks doing things like video distribution and installations that require long cable runs for a living are very resistant to installing HDMI for their customers. Many of them refuse to use HDMI because of the call-backs for HDCP-induced problems, the hassle of pulling terminated HDMI cables through walls, the inherent weaknesses of the connector, and the difficulty of finding reliable methods for running HDMI more than about 40 feet.

It's an interesting article from the perspective of describing another case where HDMI has been a pain in people's behinds. My limited experience (using HDMI with a DVI display and DVI-switching processor) suggests that for systems where the equipment rack and display are next to each other, many of the problems encountered by custom installers (cable length, multiple displays receiving signals from a centeral point) go away, making it less of a pain - but there can and will still be problems, primarily due to HDCP.
