It's a decent write up but the author doesn't seem to consider that it's a developer/enthusiast product. There will probably be a version in two - three years that with tech advances and streamlining will be much lighter and less bulky and priced more like an iphone. And I don't get the hate toward the puck, it's a good idea to keep it off the user's head, in fact I wish they'd just let the user use an iphone as the brains, with a couple specialized chips on the device, to make it more like a pair of glasses, a peripheral. But this is Apple, they like to make a device for every category rather than x-in-1 devices.
Still in the end it's a strange product for Apple, I think XR is super interesting but it's kind of dystopian, their typical plasticky advertising and "eyesight" tries to defray that but it's hard to get away from the solitary and anti-social impression of wearing a bulky pair of goggles on your head around the house. They are pretty desperately trying to find a new category to cash in on and this is what they arrived at.
