1. The iPhone replacement: Apple's smart glasses.

Apple's looking to replace the iPhone "in roughly a decade," according to a new report in The Information.

But what comes after the iPhone?

Some version of smart glasses, the first pair of which could arrive as soon as 2022, the report said. A "sleeker" pair is scheduled to arrive in 2023 — and Apple's senior managers see the headsets replacing the iPhone "in roughly a decade."

Neither product has been announced by Apple, but the two headsets were reportedly detailed to a packed room of employees in a secret October meeting at Apple's headquarters in Cupertino, California.

According to people who attended the meeting cited in The Information's report, Apple detailed the two devices as such:

The first device, expected in 2022, is said to resemble the Oculus Quest virtual-reality headset, with a high-resolution display, cameras mounted on the outside, and the ability to map its surroundings.

The second device, expected in 2023, is more akin to sunglasses, with a thick frame to house a battery and processors. These glasses are intended for all-day use and are a step closer to Apple's eventual goal of releasing a device that replaces the iPhone.

Previous reports about Apple's smart-glasses project have pointed to a release as soon as 2020. Apple has reportedly been working on some form of so-called augmented-reality eyewear since at least 2015.
