The WWDC wind-down: 5 lingering questions

3. Apple Watch for the enterprise?

Speaking of business-ready apps, it would have been interesting to see if Apple has any plans for the Apple Watch in the workplace. Sure, the announcement of watchOS 2 with support for native apps was a big deal, but the elephant in the room for enterprise users was the question of where Apple's wearable fits into their workflow.

There are already a number of apps for the Apple Watch that are useful for business users, such as Salesforce, Bottomline, and Betterworks. But imagine Apple took this unique experience and made it even better by cooking up some native Apple Watch enterprise apps with IBM. We're sure it's something that's already being discussed, and may even be in active development, but it would have been great to get even a brief acknowledgement that such apps are indeed being worked on, along with some possible applications.

4. How about a side of TouchID with my Mac?

When Apple debuted TouchID with the iPhone 5S back in 2013, it was lauded as a great security feature for both regular and business consumers alike. Fast forward another year, and that security prowess was reinforced with a higher-resolution scanner, and even became the trusted gatekeeper for Apple Pay. Frankly, it's high time Apple brought this technology to Macs in some form. Windows laptops have been integrating fingerprint sensors for years, bringing an added layer of security to those looking to keep their data free from prying eyes. Where these PC solutions have sometimes been a bit clumsy at times, TouchID on the iPhone, and now the iPad, has arguably been more accurate and elegant in its execution.

Admittedly, there are some current solutions that attempt to bring the security of TouchID to the Mac. Indeed, some iOS apps, such as MacID and Fingerkey, support using your iPhone's TouchID sensor to log into Macs without the use of a password. While these third-party solutions incorporate encryption and work over Bluetooth LE, they're just meeting a demand that could be better handled at the system level. Simply put, for those looking for an added layer of security on their Mac, built-in TouchID would be a welcome addition.

5. Where my Siri at?

Though Siri is primed to become much more useful in iOS 9 with the ability to predict what you need and when you need it, Mac users are still very much left out in the cold. And while the iPad Pro may be a twinkle in the eye of some business users looking for a portable productivity powerhouse, the fact of the matter is that most heavy work is still done well within the confines of the traditional desktop environment. Simply put, in an age when digital assistants are becoming increasingly ubiquitous, with Microsoft's Cortana making the leap from mobile to desktop in Windows 10, and Google Now serving up personalised recommendations on both Android and Chromebooks, there's no reason not to integrate Siri into OS X.

Quite frankly, what Microsoft has shown off with Cortana in Windows 10 is amazing. Now that Siri is getting smarter, think of the implications for productivity if Apple were to bring a voice-activated Siri over to the desktop. Think of a great idea while you're knee-deep in a spreadsheet? Just say "Hey, Siri, take a note." Need to quickly set a reminder for that meeting you just scheduled? Just ask Siri to set one. I don't doubt that this is in the works somewhere deep in Apple's labs, but there was palpable hope that it would be included in OS X El Capitan.
