Re: Why bang on about Apple and LIDAR
The article does seem to imply there was no AR until the LiDAR, for sure the LiDAR adds some really cool features to ARKit, but all iPhones with an A9 chip or later support AR. The newer and fancier phones have improved tracking over earlier models, but earlier models are still very good.
I think the headsets are a completely different kettle of fish. You can't carry one in your pocket.
Other manufactures of mobile devices also offer AR, and have done for roughly the same time as Apple, I just happen to be an iOS dev who works on an AR based app, so I'm biased.
Android phones also have Tof sensors, but IMO, Apples implementation of LiDAR in their dev kit far outperforms the Android equivalents
