OS X Lion is basically done, and now it has a release date. 9to5mac is reporting that Lion will "ship" (App Store download!) on July 14. It looks like the Macbook Air will also ship on the same day, but 9to5's sources weren't as certain on that front.
The news come with the caveat that any last-minute bugs can set the release back. But for now - Lion! Two weeks! [9to5mac]
