Riccardo Mori, commenting on Rick Tetzeli’s piece for Fast Company:

During the WWDC keynote, as Apple executives were outlining some of the key new features of the upcoming versions of watchOS, tvOS, Mac OS and iOS, I easily noticed a common denominator — Apple is introducing new features whose main purpose is to fix some user interface or user interaction annoyances for each of those platforms. And such improvements will not only affect a single platform, but — as Tetzeli points out — they’ll improve and solidify the interconnection between all four of them. For the first time, while watching the keynote, I found myself thinking It’d really be nice to also have an Apple TV and an Apple Watch now, the two Apple devices I usually had a very limited interest in.

It’s always been the case that Apple’s devices really shined when they were surrounded by other Apple products. But Apple seems poised to take that to an entirely new level with the release of watchOS 3, tvOS 10, macOS Sierra, and iOS 10 this fall.

A few days ago, my wife and I were discussing Apple’s typical, yearly product announcement schedule — during our weekly drive to the grocery store. My main point, at the time, was that Apple shouldn’t be announcing major upgrades to all four of their platforms at the same event.

I suggested the idea of Apple announcing major new versions of macOS and tvOS at an event in the spring and saving iOS and watchOS for WWDC. This would help spread out all the software-specific talk and leave room for hardware announcements at both events. But after reading Riccardo’s take, I’ve changed my tune.

Apple’s platforms are only going to become more tightly connected over time. This type of software development — where engineers from multiple teams work together on new features — requires a cohesive release schedule. The only way new, Continuity-like features will work is if both operating systems support the feature. And users won’t want to wait an extra three months for one of their platforms to catch up.
