Mac OS X 10.7 Lion coming summer 2011

As promised, Apple offered a preview of Mac OS X 10.7, a.k.a "Lion," which Steve Jobs says has been inspired by the company's efforts with iOS. That inspiration has resulted in an expanded use of multitouch gestures (but not on a vertical screen), an emphasis on iPad-like full screen applications, and -- here's the big one -- an App Store for OS X (which will also be coming to Snow Leopard). Also new is the Launchpad application launcher, which will give you an iPad-like grid of icons and let you create iOS-style folders for applications, and the all-new Mission Control, which offers a unified view of all your open windows, open apps, and your dock. No exact launch date just yet, but Apple says Lion will roll out sometime in the summer of 2011 -- head on past the break for the full press release.
