What about Cheetah? Actually, Apple should have used that name instead of Snow Leopard because they could have marketed it as The Cat That Runs Faster. Instead, they went with Snow Leopard which probably should have been marketed as Snow Job. 😉
Cheetah was the code name for 10.0.
Those two options on the bottom of the menu is what's new as far as I know. They are the new "Services", which haven't been accessibly through that menu before. All that's happening is that the Apple demo is showing a different service, not sure why...
I know what's new. It's just they are not present in the GM build. In fact, I can't get the new "smart services" feature to appear anywhere in the OS. Seems weird.
You would think Apple would consider this a show stopper since it's one of the few touted features. Guess not.
"The Services menu in Mac OS X lets you use features of one application while working in another. In Snow Leopard, services are more simplified, streamlined, and helpful. The Services menu is contextual, so it shows just the services appropriate for the application youre using or content youre viewing rather than all available services. You can access services with a right click of your mouse or Control-click of your trackpad.
You can configure the menu to show only the services you want, and you can even create your own services using Automator."
You can turn some of the services on by using "keyboard shortcuts" within the keyboard preference pane (even though the contextual menu is not really a keyboard shortcut), like "Add to iTunes as a Spoken Track." However, they don't have icons beside them, and it's not very elegant.
Apple clearly has some work to do on contextual services. The average Mac user is never going to find them. It's not even mentioned in the built-in help.
