Expensive but with such an immersive experience can right off the bat replace a television and surround sound system. But potentially offers a lot more than this.
Not bad for a 1st generation product.
My (and I suspect many others') main use case for a TV+surround sound system is social consumption of media. A TV I can't watch with my partner is useless, a speaker I can't use to keep a party going is useless. To me the relevant comparison here is a PC, and by that measure this is a very expensive PC with an improved screen experience. Whether that screen improvement is worth the $1K-1.5K more than a Macbook will depend on how thoroughly they've actually delivered on the AR experience.
