Because the glasses are annoying and headache inducing. That's it. No more, no less. If it weren't for that the same damn people that are bitching about how unnecessary it is would be telling me that I'm a loser for not already having a 3DTV.
The technology being used for 3D today is a dead end. As long as it depends on glasses it simply won't catch on, and there's no way to improve this technology directly so that it doesn't require glasses. Someday someone will come up with a 3DTV that doesn't use glasses and then within 10 years 2D will be as obsolete as black and white is today, but I have no idea how long it will be before we see those TVs.
Until then, don't buy into the hype put out by a bunch of companies that got used to the extra income from everyone upgrading to HDTVs and now want us to upgrade again so they can keep making big money. It's just not worth it, and it won't be until it is fundamentally changed.
