You probably heard that Apple unveiled its two new iPad tablets yesterday, the sleek iPad Air and iPad mini with Retina display. Click here for all the details on Apple's new iPads.
But maybe you missed the other big news: Apple's brand new operating system, OS X 10.9 Mavericks, is out now. If you already own a Mac desktop, upgrading to Mavericks is free! Just fire up the Apple App Store and download it.
Apple says Mavericks will make your Mac faster and more energy efficient. New technologies like Timer Coalescing, App Nap and Compressed Memory boost performance and improve battery life.
It comes with nice upgrades to classic Mac features like Safari and Finder.
Safari has been tweaked for faster browsing speeds. It has a new Shared Links feature that lets you quickly see links shared by friends on Twitter and LinkedIn. There's also a Share button that lets you instantly share Web pages on Facebook, Twitter or through email.
The Finder has always been the go-to feature for quickly locating files. Now it has tabbed windows and file tagging to make finding files even easier.
Calendar gets some nice upgrades too. It now has a travel time estimator, a map that gives you turn-by-turn directions for finding appointments and weather forecasts.
Mavericks also borrows free apps from iOS, including iBooks, Maps and iCloud Keychain. You can use these apps on your Mac and easily sync to your Apple gadgets.
