What size lens did you get, how much was it, and where from? I have a 21" and 24" LCD, wouldn't mind trying this on either one.
I got the F550 from 3dlens.com . I think it is too small for the 24 inch LCD, but should work fine on the 21 inch one provided it is a 4:3 display - but, check the length and width measurements and compare with the length and width of the F550 (check the 3dlens website).
I do miss my flat-screen CRT's though. They're easier on the eyes in some ways, I think, and they do a better job of delivering proper color with much more vibrancy and contrast - until OLED's get here anyway. Maybe this trick would be a great way to make the small-sized OLED's on the market much more useable.
Question: do they for example, mangle fine text, looking like it's very low resolution or in dire need of anti-aliasing?
They do not mangle fine text at all if you are talking about normal windows font. I regularly leave it hooked up all day long and surf websites, forums etc. There is no need for anti-aliasing as the lens performs a form of anti-aliasing itself as an added bonus. The only downside is really small dots on the screen become slightly harder to catch in a game (at least with my focal length, but I get more depth perception which is great for FPS. In IL-2 Sturmovik 1946, spotting the dot of a plane against a forest is slightly harder. In Team Fortress 2, there is nothing but big benefits. I expect the same will be true for MW:LL. In Crysis - HOLY COW the fresnel is INCREDIBLE.
Some more questions: I didn't notice seeing a firm answer on joystick support. I don't have a HOTAS Cougar, but I do have a Saitek X52. While it's software makes it rather adaptable, I do hope that I will be able to use both it and my much cheaper but surprisingly functional Logitech Wingman 3d to their full ability.
They coded in multi-axis support so I think we're in good shape here, your saitek can be programmed independently of the game software so I think we're gonna be able to do what us hotas users want to do.
And lastly, I don't get the point of the TrackIR. Granted I didn't go into all the demos and whatnot on the website, but whether it's tracking the movement of my head or my pupils, the fact is that my focus of view is no longer with my eyes and/or head pointed directly at the screen, so unless you've got your monitor mounted on rails with a motor or something on it, I can't see where this accomplishes anything of benefit, because i'm still no longer looking directly at the middle of the screen... Unless the head or pupil movements it reads are phenomenally sensitive and shift the screen position quite a great deal, I suppose...
You need to experience a Track IR firsthand to realize its potential. Trust me, I don't know a single person who, after using one for the first time wanted to go back to simming without one. They change your SA (situation awareness) forever, where you now actually have it where you didn't before. Think about this:
Imagine sitting in your mech cockpit and turning your head instantly to the side to look left and right without having to torso twist (keeping your reticle on target). With Track IR, you can do this, saving you time, effort and wasted motion. I used the glance side to side function religiously in MW2: Mercs and MW 4.
I wouldn't even think of playing a flight sim or driving sim again without it. If I do, I feel trapped an forced to look straight ahead and as if I am in some stupid console "game" rather than actually "in" the world, which the Track IR enables me to be. I don't think it is necessary for MW:LL but it'd be nifty.
If you want to see more, check out naturalpoint's website, they have videos of it working, plus there are many on Youtube (basically every FreeFalcon, OpenFalcon, Blackshark or EECH video makes use of it).
