The standard VESA mount + HDMI would probably be a better fit than having to cram everything into a SO-DIMM sized PCB. It should also work right now in most existing TVs.
True, but if they're going to insist on cramming things into the display itself it'd be an interesting way to leave them somewhat future-proofed. Personally, outside of mobile devices, I do like most others here seem to, ignore the display's capabilities and attach a computer/Roku/Apple TV/etc.
