Lion, the new version of the software that runs Apple Inc.’s Macs, is the first personal-computer operating system for the post-PC era.
The rise of smartphones and tablets, led by Apple’s own iPhones and iPads, has done more than just eat into sales of desktops and laptops. It’s made the mouse seem obsolete by allowing us to interact with our devices and data through a touch interface rather than a pointing device. Apple introduced the mouse with the original Mac. Lion largely lays the rodent to rest.
