Stereoscopic vision is effective at a distance of [distance between pupils / diameter of pupils] times that of focus.
3D on movie screens is effective, even when not simulating something super close.

3D is only one of the benefits of the device, anyway. The wide field of view and head tracking are what makes it special.

With the low resolution of the Ocular Rift, and small aperature of the human eye, I doubt focus will be an issue unless you are simulating something within arm's reach. Even then, I doubt it will be a huge issue if you don't spend to much time looking at things up close.

It can later be fixed by gaze tracking, refocusing the hardware lens on the device and rendering the focus blur in software.

Retina has a useful meaning to me: It means that the PPI has exactly doubled from all the previous products in the line*, while keeping all the GUI elements the same physical size. So it's also a software thing.
No, it's not useful when comparing with other devices, except that Apps made for Apple devices are more likely to target the exact resolution of the screen.

In the case of the MacBook Pro Retina, the longtime standard for notebooks and desktops was doubled (They tend to be close to 100dpi)

The reason for multiple sizes is so elements can be perfectly aligned to the pixel grid for maximum crispness. A vector image won't help in this case. You can lose up to half the effective resolution by not designing for an exact pixel size. Of course, this becomes less important at higher PPI.

You are false data.
