Children - and idiots - are more likely to retain all of their fingers while visiting your apartment now that Dyson introduced the Air Multiplier bladeless fan.

The major plus, according to the UK's Telelgraph, is that it's 15-times more efficient that a standard fan, which would save in energy costs, especially compared to an A/C unit. Also, it doesn't require dusting grimy blades. But, does that make it worth the heavy up-front price? We did a little math to figure out how its cost compares to the cost of a cheaper fan ...
