The 2D Project is being discontinued since thanks to improvements in software rendering technology, ALL computers will be able to benefit from Unity and the same is true of Cinnamon. This is already being felt on the new GNOME 3.4 which no longer has a fall-back mode - any one can now use the GNOME Shell without being required to have an accelerated graphics PC to benefit from the new desktop environments that have emerged in the past year or two. Thanks to Nick Rhodes for catching my error - I thought I posted a link to the Ubuntu site and I should have read it more carefully. Meanwhile, Phoronix has the story. More details here: http://www.phoronix.com/scan.php?page=news_item&px=MTE2MTQ I expect Unity and Cinnamon will also be ported to Mac OSX Intel in the future.
