New MacBook Air, Mac OS X Lion
Apple has posted the keynote video for its "Back to the Mac" event, which was held earlier today in San Francisco. The company introduced Mac OS X Lion, with many features inspired by iOS for the iPhone and iPad. The upcoming OS was previewed alongside iLife '11 and a FaceTime utility designed for video calling on a Mac.
Aside from the software, Apple unveiled two new MacBook Air notebooks. The 13.3-inch variant received several design tweaks, while an 11.6-inch model has been added to the lineup. Both Airs are already available from the online Apple Store.
