According to Apple, OS X Lion is selling faster than any other OS release in Apple’s history. Available for just $29.99, Lion adds new features like multi-touch gesture support, auto-save and auto-resume features and updated performance and usability features under the hood.

It’s been a successful week for Apple. Not only did the company report record earnings, it also released updated versions of the MacBook Air, Mac mini and Apple Cinema Display.
