Nice, so did you upgrade from the normal one yourself?
Yes, I did. I wasn't expecting it to be as big of a difference between the 2. I had a 4 sensor setup with Star tech 4 USB card, spent a lot of money getting it right with ceiling mounted cabling system and everything. Once I put on the Rift S I knew I would never go back to the Rift. And the Rift S keeps getting better with every firmware upgrade.
Oh, I should add one thing, the controllers aren't as well built as the Rift controllers. But, you get used to them.
The guardian system is amazing on the Rift S and the setup is so simple. I can move it from PC to PC in a few minutes and it remembers the play space in that other room. I think it can remember 5 play spaces.
