Mac OS X 10.7 ("Lion") will merge iOS with Mac OS X, with Apple introducing a new Mac application store, just like the iTunes App Store for iOS devices. Lion will also integrate multi-touch control and move to a new user interface like the iPad's. Lion is due for release next summer, but the Mac App Store will debut on Snow Leopard within 90 days. iLife 11 debuts today at $49, adding a number of new features to iPhoto, iMovie and GarageBand. A hi-res 13.3-inch MacBook Air comes from crossing an iPad and previous MacBook Air design, sporting a Core 2 Duo processor and solid-state storage. The 11.6-inch model starts at $999, while the top-end 13.3-inch model is $1599.
