This seems to be going by the wayside as computing power creeps up, but it'll strain your system if you want to run at anything higher than 720p for some things.
- New hardware, such as a 120(or 240) Hz display which I have no interest in buying while my current stuff works.

Of course, the cost to benefit ratio. Now let me ask you this question: as the tech continues to improve (physical display, autostereo, GPU/CPU), and your gear gets old and needs to be replaced, would you choose 3D?

I guess what I'm trying to ask is, all things being equal, would you choose 3D over 2D? I'm betting yes, but could be wrong. I suspect that most would choose 3D, but we're at an awkward transition stage in the market with this tech being new, expensive, and still rather primitive. But these variables will change in time.

When moving to colors you had to use about 3 times more bandwidth, no?

edit: not to mention the increased pixel count or reduced image resolution on the display device itself

i would rather like to see a phone with a 1080p display but i guess its limitated because of the screen size?
correct me please....

Good Point but you could wear contacts as a (poor) solution.

Also understandable, but 3d DLP projectors dont have this issue. Nor do active displays.

Your computer is only rendering 2 different Viewpoints and Page-flipping, When you consider you cant see a difference with AA on or off in 1080p, and most setups cant use AA in stereo 3d anyway, there really is no big Performance difference. Esp if your hardware can run games that high in the first place.

my guess the bigger obstacle is processing power and willingness to dare making somthing most people in the industry consider unecessary and without enough buyers or somthing

Sure, but only if it shows its value and doesn't require that I fit it. Unfortunately that seems to be a ways off, especially for glasses-free, multi-viewer systems.

All things being equal? Sure, but we're a long ways from that I suspect

I'm an early adopter, but not of just anything.

Sure, but it was transparent. Color was appended to NTSC such that new TVs could use it, old ones were still black and white, and you didn't have to wear silly glasses to view it and it worked at any normal angle. It's... not quite the same.

If I could put them in. Believe me, I've tried and failed.

I recall there being some weird skew in the 3D of Avatar reported by people who sat real close or way off to the left or right. Granted it's not going to be as drastic on a TV or home projector, but it happens. And you're still wearing glasses.

Well, you're required to basically double the base framerate. So now instead of having a floor FPS of say, 30fps it's 60. And at 1920x1080 even without AA you still need some serious horsepower in your graphics to maintain a minimum of 60fps.
