It wouldn't be an Apple keynote if playful jabs weren't thrown at Microsoft and Android over the slow adoption rates of their platforms compared to Apple's offerings.
It was left to Craig Federighi, Apple's SVP of software engineering, to deliver the blows. First up it was Android's turn, with Federighi proudly proclaiming that 83 percent of active iPhone users are running the latest version of iOS, while Google's adoption rate for Android 5.0 Lollipop languishes at 12 percent.
Next up, Federighi poked fun at Microsoft's 7 percent Windows 8.1 adoption rate, compared to Apple's 55 percent for Yosemite.
Both charts generated copious amounts of laughter that rippled through the auditorium.
But do any of these numbers mean anything in the grand scheme of things? Of course not, because it essentially amounts to little more than comparing apples to oranges. And is it really fair to look at Windows 8.1 separately from Windows 8? Probably not.
But remember that WWDC is a developer's conference, and the audience is made up of developers, and if Apple can throw up a couple of charts that make the other platforms seem less attractive to developers, it helps to starve those other platforms of new apps.
Subtle, but at the same time, very crafty.
