I own a DK2, and (unless I'm remembering wrong) paid only a bit over half of this price. A few things from my POV having had the DK2 for about a year:
1. Motion sickness is inevitable, after a lengthy playthrough, REGARDLESS of the changes made to refresh rate. This is part of the 'my body isn't physically doing what my eyes are saying,' effect. There's a scientific term for this, I'm sure, but that's the best way to explain it. More than 45 minutes inside, and I need a break, and even then I suffer from dizziness or nausea. I should mention I'm extremely into rollercoasters, rides, skydiving, etc., so it's totally cerebral of an effect.
2. Controller vs. Keyboards/Mice - So, this is debatable, for sure. However, most of you will inevitably come to conclude (I think) that sitting back with a controller is MUCH easier for you, and to show it off to others it would be nearly impossible for new people to comprehend WADS/Ctrl/Alt/Space whilst inside this tightly reformed headset. In my DK2 there's space in the bottom where I could look down and see my keyboard. As I understand it, that's no longer the case. The controller usage I was sold on within minutes.
3. The price. No. Just.. no. VR is, and still will be (for a while) a novelty thing that you are into for a few weeks, but don't really feel compelled to return to but maybe once every few months when a new, VR-specific, app or game is released. I played Alien: Isolation in it extensively, and most of the popular titles on the share/Oculus pages. They're fun, but novelty interests, at best. They've overshot here, and I can't help but think that FB and their investors are desperately attempting to grab at the massive amount of money they dumped into Oculus back then. I'm seeing a lot of guffaws elsewhere as well, outside of Blue's, and fully anticipate that initial sales will be disappointing (but not small, by any means). Give it another year or two, and time to iron out the kinks. I bet by Q4, 2016, we see a massive 'Holiday push' to sell more of these items, and by then, maybe even a firmware (or even hardware) upgrade to go along with the number of titles that will likely finally be coming out to rationalize the obscene specs and price.
That's my $20.02.
