[racket-dev] OS X 10.7 review/summary

I don't know if you folks have already seen this, but for any of you considering or using OS X 10.7, the Ars Technica review appears to contain some fairly detailed developer information.  I'm only on the second page, but table of contents entries such as "Automatic Reference Counting vs. Garbage Collection" look ... interesting.
