I'll start out by saying I love technology, and I love big TV's, HD movies and sports is awesome, but..
3DTV has got to be one of the most useless, annoying, unnecessary gimmicks that has been put on the market in a long time.
Maybe it's cause I think the quality looks worse, the price is too high, and you need overpriced glasses--
I wear glasses normally, and despite what companies say--it is not comfortable to wear the 3D glasses over your normal glasses.
I'd stick with a nice 47-52" HD 1080p Samsung any day of the week, over a 3DTV.
