rolling on the assumption that the only stupid question is the one that goes unasked....

What's the advantage of the two dots versus 1?

What is the difference (besides an extra button) on the XPS3 (NV) versus the XPS2?  I assume it changes the hologram so that it is compatible with NV goggles and/or scopes? (at a 15% upcharge, difficult to believe it incorporates NV)

I'm blind in my left eye (luckily I'm right-handed), and I've noted all the comments about keeping both eyes open while using this type of sight.  I've mounted a gun with one of these sights but have not fired one.  Sight picture looked good, see no reason why it would not work with monocular vision, but does anyone have real-world experience to confirm or deny that?

1. The 2 dots are BDC dots so you have a reference point for shooting over 300y.

2.  Correct, the only difference is the NV button.
