iCloud keychain: With iCloud keychain, Apple allows you to store all of your passwords remotely (encrypted for security purposes), so they're immediately accessible from all of your devices. So if you're accessing a site on you iPhone that you'd normally view on your laptop -- and you need to login -- you won't have to fumble around trying to remember the password. iCloud keychain does it for you.

Better laptop battery life: As users continue the shift to more mobile devices, a renewed emphasis has turned to longer-lasting batteries. Anyone who's used an iPad or the latest MacBook Air can attest to the amazing battery life these machines deliver. Mavericks looks to improve on that, using software to be more efficient with computer resources. For instance, Mavericks uses "Time Coalescing" to keep the CPU in an idle state as often as possible and "App Nap" to throttle back on the processing done in the background. Check out this PDFfrom Apple detailing Core Technologies if you want to get into the nitty gritty.

More battery info: If you're curious about which apps are hogging the most resources, in Mavericks you can simply check the Battery Menu. There's a new section that displays which app is using the most resources; or it'll show you that all apps are using nominal power. This makes it easy to see if something you're running, but perhaps not using, is sapping your battery.

Better use of Spaces: Apple has improved how Mavericks works with multiple displays, and each can be customized to show whatever you want: your desktop, a full-screen app, or multiple apps on any display. Previously, some features like the full-screen option commandeered both displays, even if only one was being used. That's no longer the case and will be a boon to multi-display users. Spaces also displays Menu bars across each display, and the Dock can be set to show on whichever display is active.

More options for AppleTV: In addition to mirroring your current desktop -- something Apple TV already does -- Mavericks will allow you to "extend" the desktop so that your HDTV becomes another wireless display. In concert with the revamped Spaces, which will allow for manual control of each display, AppleTV could make your HDTV a pretty powerful and easy-to-configure presentation tool.

Improved file sharing: File Sharing now uses the AFP and SMB protocols for sharing, and when you're connecting to a shared drive, SMB2 is now the sharing protocol of choice. This is likely an attractive feature for enterprise users, since many servers in business are Windows-based. Using the SMB2 protocol by default should make it a little easier to connect to those servers.

More cross-pollination with iOS: Apple is bringing some apps from iOS to the Mac, including iBooks and Maps. Your iBooks library can be accessed and read from the Mac, and your place in the book as well as and notes and bookmarks will sync across devices. Maps brings with it all the vector art, Yelp info open table-based back-end and 3D Flyovers that are already part of the mobile version. If you plan a trip on the Mac using Maps in Maverick, you can then send the directions to your iPhone.

Replies using Notifications: If there's a message or email you want to respond to as soon as you're notified, you can do that without even leaving another app. Just hover the cursor over the Notification icon in the upper right corner of the menubar and you'll get a Reply button. That allows you to fire off a quick response and continue working without having to switch to Messages or Mail. It's a small change, but could be time-saver for multi-taskers.

None of the changes in Mavericks represents a major strategic shift in Apple's desktop/laptop OS, but as is usually the case with each new iteration, Apple has refined OS X to make it work better for users. The eye candy has been dialed down, while better workflows and efficiencies have been built in. And the addition of iOS apps like Maps and iBooks -- combined with the ability to sync and share between desktop and iPhone or iPad -- shows that Apple is intent on taking useful features in iOS and bringing them to the desktop. The result is a thoroughly modern operation system that matches up well with iOS 7 in Apple's ever-evolving ecosystem of hardware and software.
