Rawr!
Apple previewed some of the features of Snow Leopard at the WWDC keynote. The operating system update is still being pitched as an under-the-hood refinement to Mac OS X 10.5 (Leopard); those users will be able to upgrade to Snow Leopard for $29 when it ships in September.
Snow Leopard rewrites more of the underlying technology to utilize 64-bit chips and otherwise boost speeds. Apple touts speed improvements to Mail, Preview, the Finder, the installation process, and more.
Improved multi-core support will let the OS dynamically manage multi-core threads. With Leopard, an idle program can hog the ability for the multi-core chips to execute instructions--individual treads. Snow Leopard allocates these threads so that idle apps don't waste resources.
OpenCL support lets essentially any company tap into chips that had been designed for video processing. Many graphics processors aren't taxed by general use, so software can capture these under-used resources to speed up anything.
QuickTime also gets updated with interface and tech improvements. Our favorite assists in compressing and re-encoding video for other devices, such as iTunes and iPhone.
And Snow Leopard adds Exchange support for Exchange Server 2007. This business standard will work with Mail, iCal, and Address Book to share contacts, meetings, and calendars over a network.
All together, these and other updates should improve the OS without drastically changing it... except for one more thing. Snow Leopard will work only on Intel Macs, finally ending support for PowerPC processors.
