Samsung's 3D LED TV Glasses Don't Come Cheap
Because the sets don't come with 3D glasses, you'll need to buy those separately in order to view the 3D content on the Samsung screen. Samsung's 3D active glasses (model SSG-2100AB) will cost a whopping $150 each. This means you'll need to drop an additional $600 in order for a family of four to enjoy 3D content on the new TV.

The glasses will be active 3D glasses, not the passive type like what you're accustomed to seeing at the movie theater. The liquid crystal lenses in these Active Shutter glasses change from dark to light several hundreds of times per second while communicating wirelessly with the television set. The glasses will also be able to communicate with Samsung-branded Blu-ray players and a Home Theater in Box.
In addition to the cost, there are a few other potential downfalls to Samsung's 3D TV implementation. Because of the way the content is formatted, any user without the glasses won't be able to watch the content simultaneously with users who have glasses. In addition, Samsung's glasses aren't currently available in kids' sizes and they require CR2025 batteries.
