(Which in Portal 2's case is just console text. So games not optimized for Retina yet, like Portal 2, will have teeny tiny text when displaying anything at 1:1. (fullscreen being a whopping 2880x1800 pixels) But of course, these pixels are TINY if you use 1:1 pixel. In current games, the games have access to the entire pixel resolution when in fullscreen mode. But the real question is how to handle it? Obviously at some point I think the OS X version of Löve should take advantage of this. (Without putting your nose up to the screen.)

So the pixels are really small to the point they are almost imperceptible to the naked eye at normal eye distance. The display has twice the resolution of a 1440x900 display. So instead of the menubar and titlebar being their original 22 pixel heights, they are now 44 pixels. *HiDPI Primer: Basically, the OS draws everything doubled up. This of course is a noticeable difference apparently. While older apps will simply have older resolution graphics stretched up to double the size.

Apps that are updated for Retina will have crisp smooth graphics.

Basically the OS will display things at twice its original resolution. So the new MacBook Pro has a Retina model.
