Another tip from Mac OS X Hints, this time about how with Xcode 4.1 you can enable HiDPI. I tried it out and was able put my Cinema Display into `960 x 600` HiDPI resolution. Things look amazingly huge, yet the text was crystal clear.
This should be cool once we get full software and hardware support (you know, so that we can have higher resolutions that what I tried out).
