The part you do not understand comes when you finally get 3D working, after hours of tinkering with whatever hardware you have. The real trouble with 3D has been the difficulty in getting everything in sync. Hopefully that is all about to change, and no one will have to endure the steep tech curve that 3D enthusiasts have been battling for years. 3D did not catch on because 95% of those who tried, never got to see 3D while eveything was in harmony.
I remember the first time I got my ducks all in a row, and I was in tears of joy! Seeing the 3D didn't bring on the tears, it was overcoming all the obstacles. I can say one thing though, working 3D is much like getting your first large monitor... you can never go back to a tiny 13" screen.
3D will be a trap of sorts, for many of you. Once you see it, and play your fav game with depth, and things popping out at you.... well you can try going back to standard 2D gaming after that, but it will be like going back to a 12" B/W monitor. Especially if your first taste is on some huge 60"+ screen!
Though you might have an edge, as you didn't have struggle for ages trying to get everything to play nice. How many of you care to cook on a stove, and not pop things in the microwave? You can do it, if you have the need. Maybe you could go back to 2D displays.... I know I can't/won't.
but I had the tears of joy... and you won't.
