Couldn't agree with you more! The most surreal experience is to go to a concert these days and watch the kids watching it, literally, on the screens of their smartphones (as they presumably make an unusably bad recording of it).
I always feel like grabbing them, and screaming: put down the fuc^&#! television..it's reallyhappening right in front of you!!
EVFs give me the same feeling.
That said......the sort of external monitor mentioned in Michael's review today is seriously useful, especially to MF users, where focus (i) matters more and (ii) is harder to achieve.
When you go to a concert do you yell out "turn the volume down" (insert smiley face here).
Whether one generation understands the other generation is not relevant because the next generation, is the one that we all sell to, whether your work is in a gallery, on a website, a printed page or your inventing the next new social network.
You are never going to get someone that was born in 1984 and grew up with an I-mac in their room to understand that a ground glass offers a better experience than an led/lcd and actually I'm not sure if it really does.
And I wouldn't dismiss these kids with their smart phones because even though most are just shooting a clip to put on their facebook page, there will be a few that use the experience to learn framing, composition, motion story telling that no school in the world can convey.
I have that Marshal monitor on a 5d2 that Michael reviewed and it works well, though I use it less and less as we have now moved our motion imagery to the RED (which works even better).
So my view is if your going to continue with professional image creation you have two options. Stick with the old ways and end up on the park bench, or embrace what the consumer market already understands.
I personally believe that cameras, (still and motion) have not gone future enough. You can see it with consumer cameras, they're oh so close in features, fall down in image quality but I think most of us don't realize that for all the professional systems, (canon and nikon included) we're still working with cameras that have the shape, usability very close to film cameras.
I think it's time that it all get's shaken up, but that topic is probably for another time.
