Well, 3D television has been launched, I'm sorry to say. It's estimated in five years, all televisions will have 3D capability. Now, all my teen readers are oohing and aahing and dancing and saying "cool!" and such, but wait.
I'm one of those that get a headache from watching 3D movies. Two hours of a film every couple years is sometimes worth the headache. Several hours a day in my own home? That's another thing entirely. And in case you're wondering what the headache is from, I wrote a post on my other site about it. You're actually tricking your brain and your brain is fighting back. Even if you don't get a headache from 3D, can you imagine subjecting a growing brain to it?
I'm no Luddite, but I don't think this is a good use of technology.
