I enjoyed this video, but couldn't help but think about the irony when he started talking about this being "$40" project compared to Oculus + PC ($600 + $2000) while his entire project still required a $600 iPhone and a $2000 Mac book
I'll grand you the $2600 price tag if you also tack on the 400K for the house to keep the setup dry and you assert that the creator only ever uses the laptop for this specific purpose.
You can't factor in costs like that and then critique the DIY project because of it. I'm sorry, that's just not fair.
If you already have the equipment, I don't see any difference between already owning a $600 phone and already owning a $600 vr headset. Both are probably purchased for reasons other than the DIY project
