Whether you wear glasses or not, this year's WWDC is all about augmented reality

Apple's software is good. Even as Apple has stretched its efforts across more platforms than ever  macOS, iOS, iPadOS, tvOS, watchOS, and whatever software.

It's producing for its maybe-coming-someday automobile and its almost-certainly-coming AR/VR headset  those platforms have remained good. Since Apple Maps, the biggest mistakes Apple does are like putting the Safari URL bar in the wrong place.

All that success and maturity generates a perception that Apple's software is... done, or close. In recent years, Apple's WWDC software introductions have been gradual and cumulative, with few major swings.

It's good! Apple is the software industry's finest fast-follower, adapting and polishing everyone else's new ideas quickly.

Apple will need to do more as technology evolves. AR and VR are Apple's next big thing, after the smartphone.

Apple's shown AR for years. All you see are demos, things you can do behind the camera. We don't know how the corporation plans to use AR gadgets.

Remember when Apple showed you could take a picture of a piece of paper with your iPhone and it would scan and recognise any text? completely: AR will need a simpler UI for receiving information and doing tasks.

'Don't get lost in your phone' may be a WWDC theme this year. Bloomberg's Mark Gurman says we could see an iOS lock screen that displays useful information.

I expect Apple to bring its products closer together in what they do and how they do it to make its ecosystem more usable.

With a nearly entire range of Macs and iPads running Apple's M chip and maybe a full line after WWDC if the Mac Pro finally debuts there's no reason the devices shouldn't share more DNA.

The iPhone was the last time Apple  or anyone had a truly novel gadget idea. Since then, the industry has improved and tweaked multitouch without abandoning it.
