My biggest problem with HDMI is the ongoing revision process. New technology is inevitable, and if you can't at least accept that then you're going to be needlessly unhappy a lot of the time. But new technology is at its best when it is allowed to evolve to a "sweet spot" before coming to market such that there is not a compelling need to force a new version of the same brand new technology on consumers. HDMI has not done that. It's bad enough that many early HDMI devices not make effective use of the audio channel. Even worse is the ongoing revision process - then there have been two revisions already (v1.1 and v1.2) with at least one more on the way. It's too easy to find a device that offers an HDMI connector that doesn't support all of HDMI's features (including at least a couple surround processors that offer HDMI solely for video switching). The degree of consumer confusion that HDMI has created is pretty disappointing, and the HDMI group deserves much of the blame for that.
