Apple's OS X Mountain Lion brings in some traits from Apple iOS to the desktop like with iCloud, messaging improvements, notification center, Gatekeeper, Safari improvements, etc.
For those wanting to learn more about OS X Lion, see the information at Apple.com.
As far as why Apple OS X Mountain Lion is being mentioned today on Phoronix is just to say that new OS X Mountain Lion vs. Linux benchmarks will be available on Phoronix in the near future. From earlier this year using development versions there were preview benchmarks of OS X Mountain Lion vs. Ubuntu 12.04 LTS, but new benchmarks from multiple Macs will be done in the near future for a more in-depth Phoronix comparison.
Next week I should also have a 2012 Apple MacBook Pro with Retina Display to see how well the impressive notebook display and other features work under Linux as well as the current Thunderbolt support on Linux when driving an Apple Cinema display plus other Thunderbolt-powered connectivity on Linux.
