And after you paid that you'd pay half as much again for the four graphics cards you'd need to display information on it at a decent framerate. :P

I figure by the time they can pack so many pixels into a single 30 inch display, a single graphics card will be able to drive it. Hopefully :)

  Actually, I think the screen tech is already there and it's really the terrible scaling support in OSes that is holding things back. Nobody buys high DPI displays because the experience of using one with Windows sucks. If it's true that iOS 4 automatically scales apps while improving text sharpness that will make it far more advanced than both Windows and Mac OS.

      If you have nothing useful to add to the conversation, please continue to ignore these topics. I can only assume you believe that the DPI controls in OS X and Windows are actually useful, and to that I would say: have you ever actually tried to use them?

        Do you think what you added was useful? The iOS DPI controls are some of the most shockingly rudimentary and backwards of virtually any contemporary system, which is exactly why they simply doubled each axis' pixel count (then inventing some asinine "retina display" nonsense to try to make lemonade out of the teeny screen size in the face of better equipped competitors). To see someone calling it a model to strive to is simply shocking, especially on a generally more knowledgeable site like HN. Windows has been dealing with resolution variance to much greater success since the early 90s. Seriously, by your claim, Windows XP would have been a revolution had it come with the new ability to target both QVGA and the exclusive new VGA functionality.

        The iOS DPI controls are the simplest and most straightforward of any contemporary system, which is why they will likely actually work, in contrast to the OS X and Windows DPI controls which have never worked and likely will never work. I call that more advanced. You are confusing resolution and DPI. Windows has been dealing with DPI variance by completely ignoring it since the early 90s, with the result that the physical size of interface elements varies with your screen's DPI, and high DPI displays are impractical. iOS doesn't have the option of ignoring DPI because in a touch interface the physical size of interface elements actually matters.

        >The iOS DPI controls are the simplest and most straightforward of any contemporary system But they're simple because it was a startling realization that the original design was shortsighted. The iOS platform has had a mere 3 screen attributes thus far, and each has been an essentially hard-coded hack specific for it. It is not a laudable goal. They certainly didn't spearhead density-independent layout (and are more accurately one of the last to the party). >and high DPI displays are impractical In the workstation world people generally essentially placed their display based upon its DPI. A large, lower DPI display was wall mounted or placed at a greater distance (but serving more people), while a higher DPI display came closer to the user. The iOS platform is not the best example of density-independent layout. It is one of the worst among the modern era.

For me, the real killer app of that sort of resolution would be resolution independence: current flat screens look crappy when you switch them to a non-native resolution, whereas with that sort of PPI you could get away with it - and you wouldn't even need a powerful graphics card, because the screen could appear as a lower resolution device to the system.
