Don't Buy That 3-D TV Just Yet

The box office success of "Avatar" is pushing Samsung to begin mass production of 3-D televisions, but even if the $2,000 to $4,000 initial price tag is lowered a bit, don't go buy one yet.

There are many reasons, one of the top being that any new technology always costs a lot when it first comes out and then drops in price as more people buy it. But that could take years. Just ask the early adopters of HDTVs and standard DVD players. Prices are now about as far down as they'll get, and even Blu-Ray DVD players are inexpensive.

But there are other reasons to stay away from the fun allure of being the first on your block to have a 3-D TV.
