> Do you really think that people are going to spend thousands of dollars to make homework more fun for teenagers.

Yes. Parents already routinely invest in technology to aid and stimulate their kids. Laptops are a necessity for most shoolchildren above the age of 10. A precident has been set; if the device can also be used for watching 'Avatar' on 3D Blu-ray then all the better.

>Why would people buy a double lens camera that takes pictures that need special glasses to see the image, how would you see the replay of what had just been taken on the camera screen?

Not necessarily. A lot of the new generation of stereo stills cameras use a lenticular screen to allow auto-stereo preview. In laymans terms these screens don't need glasses to view the 3D.

>Who would want to look at 3D prints of photos that require glasses to see them properly?

I predict an auto-stereo digital photo frame within the year, i.e. no need to wear glasses to view.

>What about that large percentage of the population that won't be able to see it properly because of eye defects, why would they want a set? It only needs one person in the house like that to make a 3D TV a waste of money

They wouldn't. In just the same way that people who are colour blind probably don't care too much about the colour aspect. Or people who are deaf in one ear care about stereo hi-fis. Are you really suggesting that if I go deaf in one ear I should expect my family to throw out any stereo hi-fi equipment? Anyway, statistically the vast majority of the population is fully able to experience and enjoy both colour, stereo and 3D.

>And what about the glasses? How long before people get sick of buying new ones because they've broken or lost the old ones?

I'm short sighted so wear glasses all the time, and I have to admit it's a bind. Especially when they get broken as they are expensive to replace. However, the cheapest passive 3D-glasses cost less than a dollar a piece. I'll have 10 please.

However, you could be totally right in suggesting this is another 3-D 'fad'. I guess only time will tell…

now I have to assume you are really old and quite out of touch with technology, so that's understandable. The alternative would be you failed in doing something in stereo 3D for whatever reason. So to shed some light on the matter

1) Education has changed drastically from the 50's as had homework. Kids now use products like Smart boards and software like EduSim. The educational games that are there and available on PC and the Playstation will automatically be rendered in 3D, (This is something that is done with technologies called OPENGL or DIRECX). The effect is a more immersive experience.

2) Networks like Discovery Channel will be broadcasting documentaries in 3D. If you have to learn more about animals, macro photography of insects etc, it's more absorbing when watched in stereo 3d.

3) Did you click on the link to one such camera? You can save out either a 2D or 3D image. the 3D image is not “hard baked” as you may have thought it is from the “old days” and such cameras.

4) You have obviously not enjoyed the depth of a 3D photograph or video.

5) Glasses break and so do remotes and a glass of water as well, when you get mad and throw it at the screen because you hate the “3D” content. In all cases you have to buy new ones. You'll get over it.

6) This is not the 1950s.. really, get over that too.. TUBE amplifiers died, Vinyl died, the Walkman died.. even CD died. It's MP3 for now. and it will be 3D, just as we were settling in with HD.

Best Regards.

P.s If you could re comment with a link to some online presence of youself, that would be helpful to know the authenticity/experience behind many of your claims.
