they had some 3d monitors at quakecon 07 (diff brand) and they were nice, but definately not what the cost was. The game had to be specially supported also. The graphics were iffy when it was on, and you had to wear those 3d glasses.
Its nice, but not worth it, and i got a headache to boot!
i wantone, if only they where the same price as regular monitors, samsugn has a dlp hd tv that does this there making an lcd model soon, and its just a feature so they dotn charge any extra for it the 50 inch model was 2300 i think.
