Every other year Apple releases an “S” version of the iPhone. Later this year, we’ll see the iPhone 6s and 6s Plus. The “S” models generally deliver modest improvements — better cameras, better networking, faster chips. But the basic design remains the same. The “S” suffix means the same, but better.
And so it goes with this Monday’s Worldwide Developers Conference keynote. In terms of announcements of import, WWDC 2015’s kickoff was an “S” upgrade. It built on the spectacular announcements of last year, but didn’t break huge new ground.
And that’s OK. “S” upgrades are often underrated.
