1. Mac Pro
A year ago, Apple CEO Tim Cook promised to redouble the company's efforts to maintain secrecy, something that had slipped following the loss of phone prototypes in 2010 and 2011. At its 2013 developer conference, the company headed in the opposite direction by offering a preview of the forthcoming redesign of its Mac Pro desktop computer.
There's a certain logic to the decision: Media professionals who use the Mac Pro have been pressing Apple to demonstrate its continued commitment to high-powered desktop workstations as the company's product line has become increasingly mobile-focused.
Following a lackluster Mac Pro update last summer, Cook reportedly wrote an email to one concerned customer, reassuring him that a new Mac Pro was planned for 2013. That's about as close as Apple gets to disclosing an enterprise roadmap.
The Mac Pro obviously matters to Apple, not just as a nod to the company's past, but as a proof of life: When Phil Schiller, SVP of worldwide marketing, said Apple was breaking with tradition to show off a future product, he did so in a way that was clearly intended to rebut criticism that dogged the company: "Can't innovate anymore, my ass!" Schiller declared as he showed off the forthcoming hardware.

Apple changed its name from Apple Computer, Inc., to simply Apple, Inc., in 2007, following the introduction of the iPhone. More than six years later, the company has demonstrated that it's still committed to traditional computers, even as the market moves away from them.
2. MacBook Air
It's hard to get excited about battery life. But battery life matters for mobile computer usage. If Apple's claims about the power efficiency of the latest MacBook revision prove accurate for real-world usage, the company could further distance itself from competing PC makers, which have had a hard time coming up with notebook designs as compelling as the MacBook Air.
Apple is promising all-day battery life. The company says its new 11" MacBook Air will last nine hours on battery power and its 13" model will last for 12 hours, up from about five hours. For users who can recharge their MacBook Air at night, this effectively eliminates the possibility of being without power.
Much of the credit goes to Intel's power-efficient Haswell chip set -- something competing computer makers will be using, too -- but Apple is also focusing on tuning its OS X software to use less power. The forthcoming version of OS X, known as OS X Mavericks, adds features like Timer Coalescing, App Nap and Compressed Memory to further prolong battery life on Mac notebooks. When it comes to power consumption, less is more.
3. iOS: AirDrop
Sharing files will get a lot easier under iOS 7, at least between iOS devices. A feature previously available in OS X, AirDrop, will be available on mobile devices through iOS. Apps can use AirDrop to share photos, videos or other content with people in the user's Contacts list.
Craig Federighi, SVP of software engineering, noted that AirDrop works, "no bumping required," in reference to Android's approach to local data transfers, bumping phones. Whether having to click "Accept" is any better than a physical gesture isn't immediately obvious. But AirDrop is a much needed feature in iOS.
4. iOS: Activation Lock
Smartphone thefts have surged recently and Apple has been under pressure to do something about securing lost mobile devices and data, as have competing smartphone makers.
iOS 7 offers an answer: It includes a feature called Activation Lock that prevents the Find My iPhone feature from being disabled without the device owner's Apple ID and password. It also prevents a device from being reactivated after it has been remotely erased (which can be done via Find My iPhone). While this won't make a powered-down iPhone trackable or erasable, it should make stolen iPhones less valuable to thieves.
