I'm just curious, why hasn't Apple implemented iOS' text rendering system in OS X? I can't really see a difference with the general text, but it's far better when it comes to zooming. If I try to zoom in on something in OS X, the text loses focus and becomes a total blur, whereas on iOS the blur is hardly noticeable. I don't think this is due to the Retina Display, although its been a while since I used an iDevice without it. So why doesn't Apple implement this better way of handling things across all of its devices?
