You are right, of course. Current interfaces are not well suited to high-DPI large form-factor displays. But if we wait for interfaces to happen first, I worry the wait will be prolonged.
Plus, if you gave me a 65" 400 DPI screen today, I would drop everything and immediately put it to use. I would set it up on a drafting-style standing desk and would enjoy extremely high-clarity text throughout my desktop user interface. I would hand-craft the desk myself and I'd shower you with thanks and praise.
The point being, I want to be an early adopter and hopefully there would be enough of us for the UI designers to eventually target our demographic. Right now, so much UI R&D is on small form-factor that it's a little heart-breaking to someone like myself who spends 8 hours a day working at a desktop. Science-fiction movies routinely taunt us with immersive desktop computing and we're just barely moving the needle in that direction.
"Current interfaces are not well suited to high-DPI large form-factor displays."
Actually, a simple, tiling window manager (ion3, ratpoison, OSX with SizeUP) does just fine.
I am running triple u3011 monitors with OSX Leopard, running Sizeup, and its basically like having 10 small, no-bezel displays in front of me (left and right screens are split into a quad, and middle screen is split down the middle).
Lose the gratuitous candy-UI elements and it all works just fine :)
I agree with you as well, which is why elsewhere I said I would definitely take a large high-DPI display and make it work.
Even with no change whatsoever to our current operating systems, my enjoyment of my desktop computer would increase tremendously if I could scrap my multi-monitor setup, replacing it with one high-DPI very large monitor.
But I think the point still stands that interfaces could be improved (and probably quite a bit) to take advantage of this kind of hardware. As dragonwriter said elsewhere in this thread, it may start as just simple things such as providing more flexibility on top of existing quality of life improvements that have been added to window managers based on the recognition that these monitors are larger and you can view more information at once. I would like to see such a monitor coupled with gesture input (along with mouse). I'd love to be able to do gestures to pick up a stack of windows and arrange them in a quick hand motion, for example.
Why? Just position the 65" one twice as far away and you have effectively the same pixel density with a bigger effective viewing area and less eye strain.
