Apple unveiled the latest iCloud at WWDC, with more services. What's new:

The Notes, Reminders, and Documents will be available on Mountain Lion through iCloud. Notes and Reminders, already mainstays on Apple iOS devices, will make the jump to the desktop while the new Documents integration feature will sync your personal documents across all your devices, mobile and desktop.

Notes will be able to support images and links and can be opened across multiple windows. Pages, Numbers, Preview, Keynote, Text Edit, will be made available throughout the entire Apple ecosystem.

Safari is also going to get some iCloud treatment, with the iCloud tab. The cloud button on the toolbar will pop up a list of open tabs on your other devices. So don't worry about not bookmarking a site, ever. Just don't close the window.
