There was no OS XI at WWDC. There was no plan to reinvent the wheel. The takeaway message at the launch event was simple: Apple is committed to OS X. What that means, in the long run (naming scheme aside) is that changes to the desktop will probably continue to be gradual. New features will be added and things will evolve over time. Like other recent versions of OS X, version 10.9 Mavericks follows the lead of iOS, culling from its most successful features -- though there's nothing on the order of iOS 7's dramatic redesign in store. But while the iPhone operating system seems to have taken the lead in terms of innovation, there doesn't seem to be much in the way of feature crippling in Mavericks, which some feared would come with the mobilization of the OS.
In fact, there are a number of welcome upgrades here -- things like folder tabs, tags and a more interactive Notification Center will likely improve the workflow of many Mac users. Built-in apps like Safari and Calendar have gotten nice facelifts, as well. We've spent a few days with the most recent build of OS X and are ready to give you a peek at what you're in store for, come fall. Still, knowing Apple, the company's likely still got a couple of tricks up its sleeve.
