!YES!
a year ago my daughter asked if it was worth getting a 3d tv, but we were pretty much talked out of it, since those who siad something, said they never used it.
now fast forward to this summer. I was looking for a new tv. it seems that every month there is so new tech out there, & it has come a long way even from last year. you MUST get the tv that has passive glasses, they are cheap & even can use the ones from movie theatres.
as a previous poster said, you can turn your regular tv programs into 3d.
now I bought it mainly because the olympics were shown in 3d,, really neat opening & closing ceremonies.
you can now rent 3-d movies, either from your cable tv or there is a mail program like netflix that works nicely.
IF the price diff is not that great, I'd say go for the 3-d.
