During an earnings call with Apple, the CFO nonchalantly announced that Lion is being released tomorrow.

Lion is the “big cat” name for Mac OS X 10.7, the next operating system for Mac Computers. It was announced a little while ago, and was said to be announced in “July.” Lion brings some new features in Exposé and Spaces, fullscreen apps, and an iOS-like homescreen called Launchpad.

The update will be available in the Mac App Store for $30, and there’s no more discs available.

If you have a Mac, I recommend that you read this post to make sure your mac is ready for Lion.

After using Lion for a little while, I will write a post describing the good and bad of the new features.
