Ignoring the dangers of a full dive, coma state, virtual reality such as the inability to know if someone breaks in or if your house is on fire or an earthquake, would you purchase it. Or would the idea of stimulating the 5 senses and blocking off the world seem like too much for you.
I don't know that you can just ignore that aspect of it; that's kind of the main reason I wouldn't be into something like that. Even if you want to make a huge leap and say they figured out a way to address those issues I'd still wait until it's been on the market for years and extensive testing for possible health effects had gone into it. Basically shutting out your mind for hours a day sounds like it could be problematic.
