In June Steve Jobs Announced the Newest version Of Mac OS X Snow Leopard. Snow leopard has no major new features but is a transitional releases concentrating on increasing performance in particular:

• Faster installation times and lower hard drive footprint.
• Support for up to a theoretical 16TB RAM.
• Grand Central: a parallel-programming technology that aims to have the OS take full advantage of multi-core CPUs.
• QuickTime X which will feature optimised support for modern codecs.
• OpenCL (Open Computing Language): allowing developers to code applications to use the GPU for non-graphics purposes.
• Improved Safari performance using SquirrelFish core to improve JavaScript performance by 53%. Although this Safari update will be included with Snow Leopard, it is expected to be available for OS X iPhone, 10.5 Leopard, and 10.4 Tiger.
• ZFS File system with support for storage pooling, data redundancy, automatic error correction, dynamic volume expansion, and snapshots
• Power PC Support dropped

For the printing industry this should allow applications like Photoshop to make better use of multi core systems and larger memory configurations, also the ZFS file system has a lot of advantages for professional users.
