I don't care for 3D either, although I guess if I don't have to wear the stupid headache-inducing glasses, I could change my mind.
I'm willing to wait awhile to see if the 3D craze is going to work or be a short-lived fad.
It's all about the glasses for me too. I have bad eyesight, so I would never consider getting a 3D TV if I have to wear special glasses. I've also heard about the ones that wouldn't require glasses though, as Jolene mentioned. If those become common and affordable, I could see the technology becoming much more popular.
