Well I have a 3D TV. (got it cheap because of where I work) And in my opinion and to be honest it's the biggest load of rubbish.
Yes it does look good, don't get me wrong (the family doesn't all huddled around 50 inches of plastic with sunglasses on at 9pm at night.)
My son gets a headache after only a 1/2 hour of viewing.
The 3D Discs (which you have to buy a new 3D compatible player) cost double the price of a 2D dvd.
If my son has his mates around to watch some films they have to take it in turns to share the glasses (we only have 3 pairs, I'm not going to buy extra glasses at £60 a pop for everyone that may want to come around, you can't watch a 3D title without the glasses as its all blurry)
Your lucky if the batteries in the glasses last for 4 or 5 films
The up scaled 3D content that is out there via Satellite is also pretty poor quality.
We've also tried playing some games via the X-Box on it (Avatar) well this didn't last 10 min before they were turning it off.
Just another expensive FAD in my opinion.
