Personally, I'm hoping Brilliant comes from behind and laps everyone. The tech is not particularly ambitious (more HUD than AR), but the open source philosophy is by far the best way to go.
They've got the same AR as every other pair of sunglasses, tinted lenses, plus a camera and a speaker, no? The comparison to the Vision Pro, right now, makes about as much sense as comparing the glasses to AirPods.
Meta has done a significant amount of work on a range of productivity and general computing use cases. They are clearly exploring VR/AR as a full platform, not just a game console. They have almost feature by feature parity with the Vision Pro, plus a game console on top of that.
A few examples: Their past 2 headsets have had high quality passthrough cameras for MR. Quest Pro was specifically focused on productivity in a very similar way to the Vision Pro.
2d apps are supported and quite a few are available including MS Office apps, social media and messaging apps.
I don’t know what you mean by calling desktop mirroring apps a toy since the MacBook screen mirroring is exactly one of the hallmark Vision Pro features and apps like Immersed, Virtual Desktop and Horizon workrooms do the same thing in MR or VR.
There’s keyboard and mouse support for 2d productivity and screen sharing just like Vision Pro.
They have a a corporate sales program that includes remote device management specifically for corporate and industrial use cases.
And there been quite a lot of research work on codec avatars in virtual meetings that are extremely similar to Vision Pro. This is one thing that Apple seems to be ahead of Meta on.
