I love 3D and don't mind the glasses either. But, and it is a big but, after watching Avatar in two different theaters in 3D I have to say that although I absolutely loved the film and own the DVD now, watching in 3D was an extremely painful process. I have good vision and nearly identical in each eye. I can buy and use over the counter glasses and do not require prescription, just slight magnification at close range (book, newspaper and to a lesser degree, computer). Watching Avatar in the theaters in 3D caused my eyes to tear constantly. I must have wiped my eyes 50 times during the film and it was worse the second time (a week later) than it was the first time. The film also brought on a slight but persistent headache that took an hour or so to dissipate. Meanwhile, the DVD, watched at home in HD on a 106" Da-Lite High Power with a Projector gave me absolutely no problem and the depth of the film without glasses was breathtaking, The only thing missing was the "gimmick" of phony 3-D ...the kind of 3D that does not exist in the real world. And that does not bother me either...its an experience, but its artificial and unless they make it painless, it virtually destroys the value of the medium for entertainment. I'd rather go jogging or lift weights...it hurts less.
We see in 3D and our brains will resolve it just fine, as it does every time we step out the door (or stay in!) as long as there is sufficient detail and information available. I think when 4K video hits, real 3D will be very evident to everyone, as it is already for me and many others at 1080P. So I don't have any use for the current 3D that is being marketed and when I bought a Panasonic Plasma this year, I got the single processor U50 model and am extremely happy with it and the $499 that it cost me with 12 months no interest. Panasonic wised up part way into the year...competitors less expensive "regular" plasmas were outselling Panasonic's much more expensive ST, GT and VT series. Basically, if they continued to insist on 3D, they were losing customers for the current generation and the next generation. The 3D push was a marketing play supported by the movie industry that is concerned with not just copyright, but also keeping the viewing public going to the theater.
For the first time, we can produce at home a video and audio experience comparable to the best theaters and not for a huge outlay either, just carefully chosen and assembled equipment. I'm not against 3D but let the people decide. If Panasonic had not come out with their U50, I might have bought a Samsung or might just keep watching the 32" CRT for the NEWS and continue watching the 106" screen for movies and sports.
Presently, I am augmenting my "Home Theater' with 2 centers, 4 fronts (upper and lower), double subs, 2 side surrounds and 2 back surrounds along with two pairs of speakers for just music. I have seriously considered a 9.2 channel Pioneer Receiver. "40% of a film is the score"...Sergio Leone said that and I think he was absolutely right. If you want to augment your immersion and enjoyment in cinema and sports, do it with great sound and a bigger screen. The "real" 3D will be there if the detail, color and shading is there. And the 3D sound will make it even more real.
