I got my hands on the Developer Preview of Mac OS 10.7 Lion, and in addition to writing up my thoughts on the new features, I also made this 5 minute video. In the video I bring you a closer look at Mac OS X 10.7 so you can see all the fancy newness and things I talked about in the Mac OS X 10.7 walkthrough.
Features covered in the video include the improved gesture support, mission control and launchpad, the newly redesigned Finder, upgrades to Mail.app and other Mac OS X core apps, as well as built-in auto save and app freezing functionality.
For the best experience, I recommend watching the Mac OS X Lion walkthrough video in full-screen HD.
