Screens "retina" in Mac?

And if the Mac goes to a screen "Retina", or at least a screen high definition? Several indications suggest that Apple thinks. The company is the first to have proposed a screen of 30 inches in June 2004 and Mac OS X Lion shows that it is possible to go further. The first is that the screen's default system, Mount Fuji, is an image 3200 x 2000 while other images are 2560 x 1600, like all wallpapers Official Apple since Mac OS X Tiger.

The second is that the system incorporates a new mode, the HiDPI. Typically - a classical system - the interface elements have a fixed size in pixels and displayed varies depending on the screen. A screen 15-inch 1024 x 768 display so large interface elements, a screen 17-inch 1920 x 1200 displays small interface elements.

If it is possible to play on the vector components, such as text, the majority of icons and menus are in bitmap resizing and resent. With mode HiDPI, Apple will actually do the same thing on 4 with the iPhone screen Retina: each element "bitmap" version will have a "2x @" which is two times larger in height and width .

This system can offer screens with double the resolution (and therefore thinner visually) while maintaining a usable interface for the common man. Of course, this solution is only a stopgap and an entirely vector would be the best solution, but neither Apple nor Microsoft seem to be able to offer this kind of thing ...
