The UI elements are significantly smaller. They have to be if you’re increasing the pixels, but not the actual physical size of the display.
This is obvious and the main reason why I thought those displays would only be possible in the far future. Current operating systems are not flexible enough to handle fully scalable fonts, icons and images. Too much pixel data, too few vectors.
Apple managed to avoid this problem on the iPhone because it exactly doubled the resolution.
Yeah, right! That would be a smart solution for bigger displays too, wouldn’t it? Double everything. You might loose some screen estate compared to current high-resolution-displays but I imagine that would be worth it.
