I must confess I'm not much of a fan of scaling, much as it looks good there's always something...
The 21.5" and 24" at 4K make sense, and considering the arguments presented here so does the 27" 5K in fact. I'm starting to think that's the one I want now :-(
And it will probably be the one Apple will do for sure.
They could make the 24" 4K also, but I find it hard to believe, since they seem to be focused on larger panels. Surely no 21.5" 4K I'd say, although it could come to the iMac.
The current TBD looks really nice at 2560x1440, going Retina would make it gorgeous.
The fundamental problem is the card driving it. It would be like driving 2 panels, and we all know the problem AMD has with multi-monitors, power draw goes up considerably. It seems better with Fury but still nowhere near NVidia.
ixxx69, indeed a waste was not a good way to put it. What I was trying to say is that you still need to pump out 4K worth of pixels, and you either get a desktop that looks like 1080p (with big UI elements on that size, but very sharp) or use the full resolution, which is great, but things start to get very small.
Any option seems ok with me actually, but something in the middle would also be nice. And that actually might be Retina 2560x1440 or 5K.
Come on Apple, tell us something...
Leaks, anyone? Apple seems to have all very well contained. Or have nothing at all in the works...
