I'll definitely scrape some money together to get this once the retail version is out (I was staring at the website's dev kit pre-order page a few weeks ago until I finally came to my senses). The only thing I'm worried about is that I'll probably need to upgrade my PC along with it.
But wow, the flying bit in the video - I get a tingly feeling just trying to imagine what it must be like!
On a side note, I wonder how effective extended "flying" would be for reducing a person's fear of heights? We're just looking at it from a gamer's perspective, but I can picture all types of uses popping up for this thing - and yes, once the porn industry finds interest in this, it'll certainly accelerate the development for this type of technology.
