15 machines? Do you use a rack? Seriously though much like the other responder hdr and actually most video things are not important to me and I tend to adopt them only when they are on the most affordable of options. Granted there are certain things important to me that I will go for earlier. Energy efficiency or more environmental disposal wise (have not yet encountered anything that significantly is but it would sway me). Also I have wanted to get organic leds because having very black blacks is a big deal for me. So basically I guess im saying I mostly don't care about that stuff.
