On the whole, WWDC 2015 brought less news and less change than its two immediate predecessors. Apple is still on top of the world, but this year, it’s about refining and polishing, not wide-reaching changes. – WWDC 2015 Debrief — 512 Pixels
I didn’t get to attend as much WWDC as I would have liked, as I flew across the country for some meetings and an NBA Finals game in Cleveland part way into the week. I would overall say that the atmosphere seemed a little more subdued in years past, yet didn’t lack the enthusiasm that comes with these Apple events either. It’s a recognition that things are evolving, they are the biggest company in the world, and there’s a need to go back and dot some i’s, albeit without admitting that they weren’t dotted in the first place.
I’m looking forward to the iPad enhancements, and to the watchOS (rhymes with nachos) with real apps etc. I’m worried about the strain this puts on developers with limited resources at the same time.
