I threw this together to try out Revolution R.

The thing that jumped out at me is Multithreaded Performance. I've fooled with *apply, parallel and segue in the past and anything which promises an innate boost is interesting.

A quick run of the linked R-benchmark 2.5 pretty cleanly demonstrates the benefits.

Running on my i7 960 desktop.
