I'm an old gut too but I hate seeing a response referring to a 3D movie seen 20 or 30 years ago and thinking that is today's 3D. If you haven't seen Avatar in 3D then you cannot even fathom the differences between then and now.
That's precisely the movie I watched and was underwhelmed with. Not that the clarity and the movie itself wasn't spectacular, but that the brand new $3500 HDTV I was contemplating flickered with the glasses.
But I digress, I suspect your comment wasn't directed towards me, but to those that had not actually sat and tried the tech.
I did, and it's a mater of both opinion and watching out for the health needs of my spouse and family. Seriously, serious headaches and potential seizures are not going to encourage the WAF in a positive direction for this tech. It just cannot flicker "AT ALL" before I can purchase it.
So it's currently a pricy high-tech "toy" and not true enthusiast in my opinion "YET". When the frequency of the image alternation is ramped up much higher so it's not visually perceptive, then I'll be the first in line.
