One of the developers that attended WWDC takes us on a screenshot tour of the new Leopard features. Some of the more interesting features are Spaces, which lets you define up to 16 virtual desktops to place your applications on, to-do lists in Mail.app, and Dashboard service features in Safari.
There’s also miscellaneous stuff like iChat getting Mail’s look, more search criteria in Spotlight, and making notes in Preview. Wander over to Hardmac to get a full pictured-preview.
