1) Are you currently using HDMI?
Not quite yet.
2) What devices you have use HDMI? Do they work well together?
Have 2 HDTVs, a Sony and JVC. Just got an HDTV cable box, but it has DVI output -- need to get an adaptor.
3) If you are not currently using it, are you planning to upgrade? Why or why not?
Yes, currently shopping for AV receiver and DVD player. Main goal is better video images, especially upconverting standard TV and DVDs to better match the screen resolution on my LCDs.
4) What do you think is the most exciting feature of HDMI 1.3?
I dunno; I barely know that there are multiple versions. If this were a multiple choice question, I'd take a guess.
