Passage Summary: An article says most companies shouldn't buy this tech, but the author disagrees because companies that already bought it like it.

Conclusion: The magazine's claim that buying videoconferencing equipment is a waste of money is incorrect.

Reasoning: A survey of companies that already purchased the equipment found that most of them believed the investment was worth the cost.

Analysis: The author is making a classic sampling error by looking only at 'success stories.' Companies that have already purchased the equipment are likely those that had a specific need for it, making them a biased group to use when predicting whether it would be a waste for *other* companies. It's a bit like asking people at a steakhouse if they like meat to prove that everyone should eat there—you're ignoring the people who stayed home because they're vegetarians. Look for an answer that points out this failure to consider how the surveyed group differs from the general population.
