Today is the Day! Apple introduced OS X Lion to the Mac App Store. Not only that, they released the first Mac ever to come with it -- a new and improved Macbook Air with Core i5 processors and a backlit keyboard. This looks like it's going to be the new replacement for the white Macbook, as Apple has now discontinued it. Also, they have added Thunderbolt ports to the new 27" displays. A good day for Apple fans indeed!
