Wikipedia in Dictionary
Harness the power of Wikipedia when you're connected to the Internet — it’s built right into Dictionary. You get a great Mac OS X user interface with super-fast searching and beautifully laid out-results.

Japanese-English Dictionary
Translate English to Japanese and vice versa. This capability is now built into the Leopard Dictionary.

Path Bar
See the path of a file when you view it in the Finder. Just choose Show Path Bar from the View menu and the path is visible at the bottom of the Finder window. You can also drag files to any location in the Path Bar.

Folder Sharing
Turn any folder on your Mac into a shared folder. You can share any folder in your home directory from the Sharing system preference. You can customize access privileges and even authorize specific contacts in your Address Book.

Printable Font Book
Print out comprehensive previews of your fonts, including sample text in varying sizes or all available glyphs. Just select fonts in Font Book, choose Print from the File menu, and select any of the three built-in report types.

Language Collection
Quickly access the fonts you use most often. Fonts are grouped according to your default language preference.

Font Auto-Activation
Automatically activate fonts as you need them. When an application requests an installed font that’s currently disabled, Leopard activates that font and keeps it active until the requesting application quits.

Recording
Save your audio and video chats for posterity with iChat recording. iChat asks your buddies for recording permission before the chat starts, then stores completed audio chats as AAC files and video chats as MPEG-4 files — so you can share with others or sync to your iPod.

Russian Localization
Mac OS X Leopard is fully localized in the Russian language.

Russian Spell Checker

PDF Manipulation in Preview
Re-create your PDF as you like. Move individual pages around, or remove pages altogether. You can even combine PDFs with a simple drag and drop.

Printer Drivers via Software Update
Make sure you always have the latest printer drivers. Download directly to your system using the familiar capabilities of Software Update.

Application-Based Firewall
Gain more control over the built-in firewall. Specify the behavior of specific applications to either allow or block incoming connections.

Live Partition Resizing in Disk Utility
You may be able to gain disk space without losing data. If a volume is running out of space, simply delete the volume that comes after it on the disk and move the volume’s end point into the freed space.

Guest Log-In Accounts
Allow anyone to surf the web and check email as a guest on your Mac. When they log out of the guest account, Mac OS X purges the account, removing any trace of their activity. So each time someone logs in as a guest, he or she gets a fresh, unused account.

Scroll Non-Active Windows
Scroll any open window, even if it’s not active. Simply position your mouse over the target window and scroll.

Empty Trash Button
Empty the Trash from the Trash itself with the Empty Trash button.

Eject All Partitions
Enjoy greater flexibility when ejecting a partitioned USB or FireWire volume. You can eject just one of the volumes or all the volumes at once.

Improved International Support
Get more out of Terminal. The Core Text API for text layout reduces setup time and makes Terminal behave flawlessly for international users, with an increased character set.

OpenDocument and Word 2007 Formats
Take advantage of TextEdit support for the Word 2007 and OpenDocument formats for reading and writing.

AutoFS
Automatically mount and dismount network filesystems on separate threads to improve responsiveness and reliability.

Wide Area Bonjour
Access your Macs, at home or on the road, with a single consistent host name. Use this host name whether you’re behind a NAT gateway or hopping across DHCP servers.

Directory Utility
Graphically manage all local and remote directory entries and services in one place. You don’t have to rely on complicated command-line operations.

Ruby on Rails
Work in a developer's dreamland. Leopard is the perfect platform for Ruby on Rails development, with Rails, Mongrel, and Capistrano built in.

Много еще чего обещают, что покажется кому то важным — мерял по себе.
Многое из обещанного так или иначе можно реализовать сегодня, но все же в основном через одно место.
Так что теку слюнями и жду волшебных коробок.
