You are still resolution dependent. The size of things still matters for the rez of the display, there's just now two classes of it: Normal and high. What this means is you don't get proper scaling of things on arbitrary displays. Like let's say you get a high end DM-3428 desktop 4k display. It's a 28" 4k monitor, 150 PPI. Ok great, however things will be too small if you operate normal programs at its full rez. So you do half-rez ala Apple... Except that is now 75 PPI. Way too large (93ish PPI is normal for like a 1920x1080 24" monitor).

What you need is an intermediate scaling ratio. You need to be able to go resolution independent and say "This display is X inches large and Y resolution, you work it out to display things right." That way you can do any resolution/size combo you want.

That was why I said earlier I don't know how to feel about Apple's HiDPI stuff. I like the idea of pushing higher rez displays, now that we have the technology to realistically do it, but their doubling method is problematic long term, it doesn't solve the problem of resolution dependance and in fact makes it works in a way.
