What's new and advanced about this? Hasn't it all already existed in some form? It's just been Apple-ified, no? It's just a VR headset, an actual AR headset is something like HoloLens.
Beyond the tech, who is even the target audience for this? I only see it as a gimmick, one for just Apple geeks to buy. One of the reasons 3DTV's failed is because nobody wanted to wear the glasses, so why would anyone want to strap this to their face just to do something they already do or could do on their TV/computer/phone?
You can already pretty much do everything this can with an existing VR headset in one way or another, for a lot cheaper.
It's a bizzare product.
Maybe try looking for some Keychron boards on ebay? They should be around that price used and a lot of them are wireless too.
