Well it looks like the cat's finally out of the bag virtual box. Apple CFO Peter Oppenheimer just confirmed during today's earnings call that Mac OS 10.7 is due to hit the Mac App Store tomorrow, making Lion available as a 4GB download for $30. The new operating system packs 250 new features, including an iOS-like app launcher, multi-touch gestures, AirDrop for direct file sharing, and system-wide Resume. More enhancements that will feel particularly familiar to iOS users include a new version of Mail with conversation view, and reverse touchpad scrolling. We'll have a full review of Lion later this week, but check out our hands-on preview for our initial impressions. Want to collaborate on projects with multiple machines? Lion Server will also be available as a $50 download -- for those of you that need to support an entire pride.
