It'll probably go like this:
1) NSA gets first dibs (the manufactory is in Utah; so is NSA's datacenter)
2) Then HPC at universities
3) Then the high-end enterprise market (Stack Exchange might buy one), plus anyone from the consumer space willing to pay
4) Then it'll truly be affordable for "well-off" consumers
5) 10 years from now it might be affordable for "poor" consumers on low-end devices
6) 20 years from now I might get it on my desktop at work
