Bertrand Serlet, Apple's senior vice president of Software Engineering made the following statement's in a press release:

"We've built on the success of Leopard and created an even better experience for our users from installation to shutdown,".
"Apple engineers have made hundreds of improvements so with Snow Leopard your system is going to feel faster, more responsive and even more reliable than before."

To create Snow Leopard, Apple engineers focused on perfecting the world's most advanced operating system, refining 90 percent of the more than 1,000 projects in Mac OS X. Users will notice the following in the new operating system:

• a more responsive Finder
• Mail that loads messages 85 percent faster and conducts searches up to 90 percent faster
• Time Machine with up to 50 percent faster initial backup
• Dock with Exposé integration
• a 64-bit version of Safari 4 that boosts the performance of the Nitro JavaScript engine by up to 50 percent and is resistant to crashes caused by plug-ins

64-bit and 32-bit compatibility
For the first time, system applications including Finder, Mail, iCal, iChat and Safari are 64-bit and Snow Leopard's support for 64-bit processors makes use of large amounts of RAM, increases performance, and improves security while remaining compatible with 32-bit applications. Grand Central Dispatch (GCD) provides a revolutionary new way for software to take advantage of multicore processors. GCD is integrated throughout Snow Leopard, from new system-wide APIs to high-level frameworks and programming language extensions, improving responsiveness across the system. OpenCL, a C-based open standard, allows developers to tap the incredible power of the graphics processing unit for tasks that go beyond graphics.

Microsoft Exchange Server support
Snow Leopard builds support for Microsoft Exchange Server 2007 right into Mac OS X Mail, Address Book and iCal so you can use these applications to send and receive email, create and respond to meeting invitations, and search and manage your contacts with global address lists. Exchange information works seamlessly within Snow Leopard so users can take advantage of OS X only features such as fast Spotlight™ searches and Quick Look previews. Snow Leopard is the only desktop operating system with out of the box support for Exchange 2007 and businesses of any size will find it easier to integrate Macs into their organization.

Users with special needs
Every Mac includes innovative features and technologies for users with special needs, and Snow Leopard adds groundbreaking new features that make the Mac experience even more accessible to those with a vision impairment. Apple's Multi-Touch™ trackpad is now integrated with the VoiceOver screen reader so users can hear and navigate different parts of a window or the desktop by moving a single finger around the trackpad as if it were the screen. Snow Leopard also introduces built-in support for wireless bluetooth braille displays and the connection of multiple braille displays simultaneously to one Mac.
