Because OS X Mountain Lion is stable and pretty decent, there is much less urgency with upgrading to Mavericks, but you probably should anyway.
Beyond the general improvements and new features available, it’s also just good practice to keep your Mac software up to date, both for individual apps and for the core OS.
Get in the habit of updating, your computer will thank you for it.
Though you should take a series of steps before upgrading to Mavericks, if you do nothing else – back up the Mac with Time Machine.
Google is updating Android without actually updating the Android operating system.
When a manufacturer wants to release an Android device, they have to negotiate an agreement with Google to get the Google Play Store and Google apps on their devices.
As part of this agreement, Google reserves the right to update the Google Play Services component of Android on their own.
The company can squash certain bugs and even introduce new features just by updating Play Services.Similarly, Google has also added an app-scanning feature that watches for malware, making older devices more secure.These user-facing features were added to the Android operating system via a Play Services update without any interference from device manufacturers or carriers.Between the crashes, the crazy unpredictable auto-saving behavior, the aggressive file locking and forced file duplication, and the removal of simple yet core functionality and features like Save As, many Lion users were annoyed to say the least. All of those issues were mostly fixed with OS X Mountain Lion, and has been reiterated on further with OS X Mavericks.Things are better now, so if the holdup has been fear of making things worse, it’s unfounded.If you're using an older version of OS X, updates are handled through the Software Update utility.
