the only time I watched something with actuators in my seat was when I was at a summer camp at a local museum 6 years ago, it was a short F1 (formula one) film.
On the subject of 3DTV, I saw a demo of 3DTV today at a tech shop, I wasn't impressed at all with the 3D, it looked really flat, and it looked too unreal (well, I was watching "Monsters vs Aliens" in that demo)I checked with both pairs of glasses, same result. You need those weird battery-powered glasses as well, and in my point of view, it's not worth it.
Stores are selling 3DTVs for $2,000 each. I honestly think paying two thousand dollars for a pointless feature for a TV is overkill. When this technology started getting into computers, there was a big boom in 3DTV promotion imo. NVidia is going crazy about it.
I have a 37" HDTV at home, and a HD cable box, and it's not much better compared to Standard-def. I watch standard-def on it too. At least i'm happy now.
The main reason why I use LCDs is because they use less power, (both my PC's monitors are LCDs, one is from when LCDs were new, and one is from the past few months. my new one is energy star certified. another reason is that they don't have that annoying ringing noise CRTs have.
