It's more than I expected (I was guessing ~$400), but I can't say that I am all that surprised or outraged. For a long time, the Oculus folks insisted that they were going to focus on making it good, not making it affordable. This makes sense, because VR technology has been around for decades, but nobody has really managed to make a GOOD VR set prior to the Oculus. Assuming the consumer version is in fact good, they can then focus on making it affordable. If you want affordable, there's always the cardboard VR sets to play with.
If they manage to succeed with making a good set, then VR will start to catch on and prices will fall for other good sets. I wouldn't be surprised if Oculus eventually releases different models to fulfill low and high end price points.
I also don't understand the outrage over the PC specs. The fact of the matter is that based on years of testing, it was determined that you really needed high resolution (i.e. 4k) to get rid of the screen door effect that has always been the bane of VR implementations. I wouldn't be surprised if 8k will be needed to really get rid of it. That takes a lot of computing horsepower and there just isn't any way around it.
